 A warning for models with melt transport: In models with fluid flow, some compositional fields (in particular the porosity) might be transported with the fluid velocity, and would need to set the constraints based on the fluid velocity. However, this is currently not possible, because we reuse the same matrix for all compositional fields, and therefore can not use different constraints for different fields. Consequently, we set this parameter to true by default in models where melt transport is enabled.

 Whether to make the grid by gluing together two boxes, or just use one chunk to make the grid. Using two grids glued together is a safer option, since it forces the boundary conditions to be always applied to the same depth, but using one grid allows for a more flexible usage of the adaptive refinement. Note that if there is no cell boundary exactly on the boundary between the lithosphere and the mantle, the velocity boundary will not be exactly at that depth. Therefore, using a merged grid is generally recommended over using one grid. When using one grid, the parameter for lower repetitions is used and the upper repetitions are ignored.

 If compositional fields are used, then one would frequently want to make the density depend on these fields.

 Freezing rate of melt when in subsolidus regions. If this parameter is set to a number larger than 0.0, it specifies the fraction of melt that will freeze per year (or per second, depending on the ``Use years in output instead of seconds&apos;&apos; parameter), as soon as the porosity exceeds the equilibrium melt fraction, and the equilibrium melt fraction falls below the depletion. In this case, melt will freeze according to the given rate until one of those conditions is not fulfilled anymore. The reasoning behind this is that there should not be more melt present than the equilibrium melt fraction, as melt production decreases with increasing depletion, but the freezing process of melt also reduces the depletion by the same amount, and as soon as the depletion falls below the equilibrium melt fraction, we expect that material should melt again (no matter how much melt is present). This is quite a simplification and not a realistic freezing parameterization, but without tracking the melt composition, there is no way to compute freezing rates accurately. If this parameter is set to zero, no freezing will occur. Note that freezing can never be faster than determined by the ``Melting time scale for operator splitting&apos;&apos;. The product of the ``Freezing rate&apos;&apos; and the ``Melting time scale for operator splitting&apos;&apos; defines how fast freezing occurs with respect to melting (if the product is 0.5, melting will occur twice as fast as freezing). Units: 1/yr or 1/s, depending on the ``Use years in output instead of seconds&apos;&apos; parameter.

 Freezing rate of melt when in subsolidus regions. If this parameter is set to a number larger than 0.0, it specifies the fraction of melt that will freeze per year (or per second, depending on the ``Use years in output instead of seconds&apos;&apos; parameter), as soon as the porosity exceeds the equilibrium melt fraction, and the equilibrium melt fraction falls below the depletion. In this case, melt will freeze according to the given rate until one of those conditions is not fulfilled anymore. The reasoning behind this is that there should not be more melt present than the equilibrium melt fraction, as melt production decreases with increasing depletion, but the freezing process of melt also reduces the depletion by the same amount, and as soon as the depletion falls below the equilibrium melt fraction, we expect that material should melt again (no matter how much melt is present). This is quite a simplification and not a realistic freezing parameterization, but without tracking the melt composition, there is no way to compute freezing rates accurately. If this parameter is set to zero, no freezing will occur. Note that freezing can never be faster than determined by the ``Melting time scale for operator splitting&apos;&apos;. The product of the ``Freezing rate&apos;&apos; and the ``Melting time scale for operator splitting&apos;&apos; defines how fast freezing occurs with respect to melting (if the product is 0.5, melting will occur twice as fast as freezing).

 If compositional fields are used, then one would frequently want to make the density depend on these fields. In this simple material model, we make the following assumptions: if no compositional fields are used in the current simulation, then the density is simply the usual one with its linear dependence on the temperature. If there are compositional fields, then the material model determines how many of them influence the density. The composition-dependence adds a term of the kind $+\Delta \rho \; c_1(\mathbf x)$. This parameter describes the value of $\Delta \rho$. Units: \si{\kilogram\per\meter\cubed}/unit change in composition.

 Add an adiabatic temperature gradient to the temperature used in the flow law so that the activation volume is consistent with what one would use in a earth-like (compressible) model. Default is set so this is off. Note that this is a linear approximation of the real adiabatic gradient, which is okay for the upper mantle, but is not really accurate for the lower mantle. Using a pressure gradient of 32436 Pa/m, then a value of 0.3 K/km = 0.0003 K/m = 9.24e-09 K/Pa gives an earth-like adiabat.Units: \si{\kelvin\per\pascal}.

In complex models the factor can be increased further to improve convergence behaviour. As the stabilization factor increases, the effective viscosity gets smaller, and is balanced by an increasing body force term.

This is useful because in some models the melt velocity can have spikes close to the interface between regions of melt and no melt, as both $K_D$ and $\phi$ go to zero for vanishing melt fraction. As the melt velocity is used for computing the time step size, and in models that use heat transport by melt or shear heating of melt, setting this parameter to true can speed up the model and make it mode stable. In computations where accuracy and convergence behavior of the melt velocity is important (like in benchmark cases with an analytical solution), this parameter should probably be set to &apos;false&apos;.

Note that the number of particles per processor is not affected by the seed.

+This parameter is used to decide which method to use to solve the equation that describes the position of particles, i.e., $\frac{d}{dt}\mathbf x_k(t) = \mathbf u(\mathbf x_k(t),t)$, where $k$ is an index that runs over all particles, and $\mathbf u(\mathbf x,t)$ is the velocity field that results from the Stokes equations.
+
+In practice, the exact velocity $\mathbf u(\mathbf x,t)$ is of course not available, but only a numerical approximation $\mathbf u_h(\mathbf x,t)$. Furthermore, this approximation is only available at discrete time steps, $\mathbf u^n(\mathbf x)=\mathbf u(\mathbf x,t^n)$, and these need to be interpolated between time steps if the integrator for the equation above requires an evaluation at time points between the discrete time steps. If we denote this interpolation in time by $\tilde{\mathbf u}_h(\mathbf x,t)$ where $\tilde{\mathbf u}_h(\mathbf x,t^n)=\mathbf u^n(\mathbf x)$, then the equation the differential equation solver really tries to solve is $\frac{d}{dt}\tilde{\mathbf x}_k(t) =  \tilde{\mathbf u}_h(\mathbf x_k(t),t)$.
+
+As a consequence of these considerations, if you try to assess convergence properties of an ODE integrator -- for example to verify that the RK4 integrator converges with fourth order --, it is important to recall that the integrator may not solve the equation you think it solves. If, for example, we call the numerical solution of the ODE $\tilde{\mathbf x}_{k,h}(t)$, then the error will typically satisfy a relationship like \[  \| \tilde{\mathbf x}_k(T) - \tilde{\mathbf x}_{k,h}(T) \|  \le  C(T) \Delta t^p\] where $\Delta t$ is the time step and $p$ the convergence order of the method, and $C(T)$ is a (generally unknown) constant that depends on the end time $T$ at which one compares the solutions. On the other hand, an analytically computed trajectory would likely use the \textit{exact} velocity, and one may be tempted to compute $\| \mathbf x_k(T) - \tilde{\mathbf x}_{k,h}(T) \|$, but this quantity will, in the best case, only satisfy an estimate of the form \[  \| \mathbf x_k(T) - \tilde{\mathbf x}_{k,h}(T) \|  \le  C_1(T) \Delta t^p  + C_2(T) \| \mathbf u-\mathbf u_h \|  + C_3(T) \| \mathbf u_h-\tilde{\mathbf u}_h \|\] with appropriately chosen norms for the second and third term. These second and third terms typically converge to zero at relatively low rates (compared to the order $p$ of the integrator, which can often be chosen relatively high) in the mesh size $h$ and the time step size $\\Delta t$, limiting the overall accuracy of the ODE integrator.

+A comma separated list of particle properties that should be tracked. By default none is selected, which means only position, velocity and id of the particles are output. 
+
+The following properties are available:
+
+`composition&apos;: Implementation of a plugin in which the particle property is defined by the compositional fields in the model. This can be used to track solid compositionevolution over time.
+
+`cpo bingham average&apos;: This is a particle property plugin which computes the Bingham average for the Crystal Preferred Orientation particle property plugin so that it can be visualized.
+
+`cpo elastic tensor&apos;: A plugin in which the particle property tensor is defined as the Voigt average of the elastic tensors of the minerals in the textured rock.Currently only Olivine and Enstatite are supported.
+
+`crystal preferred orientation&apos;: WARNING: all the CPO plugins are a work in progress and not ready for production use yet. See https://github.com/geodynamics/aspect/issues/3885 for current status and alternatives. The plugin manages and computes the evolution of Lattice/Crystal Preferred Orientations (LPO/CPO) on particles. Each ASPECT particle can be assigned many grains. Each grain is assigned a size and a orientation matrix. This allows for CPO evolution tracking with polycrystalline kinematic CrystalPreferredOrientation evolution models such as D-Rex (Kaminski and Ribe, 2001; Kaminski et al., 2004).
+
+`elastic stress&apos;: A plugin in which the particle property tensor is defined as the total elastic stress a particle has accumulated. See the viscoelastic material model documentation for more detailed information.
+
+`elastic tensor decomposition&apos;: A plugin which decomposes the elastic tensor into different approximations (Isotropic, Hexagonal, Tetragonal, Orthorhombic, Monoclinic and Triclinic) and provides the eigenvectors of the tensor.
+
+`function&apos;: Implementation of a model in which the particle property is set by evaluating an explicit function at the initial position of each particle. The function is defined in the parameters in section ``Particles|Function&apos;&apos;. The format of these functions follows the syntax understood by the muparser library, see {ref}\`sec:run-aspect:parameters-overview:muparser-format\`.
+
+`grain size&apos;: A plugin in which the particle property is defined as the evolving grain size of a particle. See the grain_size material model documentation for more detailed information.
+
+`initial composition&apos;: Implementation of a plugin in which the particle property is given as the initial composition at the particle&apos;s initial position. The particle gets as many properties as there are compositional fields.
+
+`initial position&apos;: Implementation of a plugin in which the particle property is given as the initial position of the particle. This property is vector-valued with as many components as there are space dimensions. In practice, it is often most useful to only visualize one of the components of this vector, or the magnitude of the vector. For example, in a spherical mantle simulation, the magnitude of this property equals the starting radius of a particle, and is thereby indicative of which part of the mantle a particle comes from.
+
+`integrated strain&apos;: A plugin in which the particle property tensor is defined as the deformation gradient tensor $\mathbf F$ this particle has experienced. $\mathbf F$ can be polar-decomposed into the left stretching tensor $\mathbf L$ (the finite strain we are interested in), and the rotation tensor $\mathbf Q$. See the corresponding cookbook in the manual for more detailed information.
+
+`integrated strain invariant&apos;: A plugin in which the particle property is defined as the finite strain invariant ($\varepsilon_{ii}$). This property is calculated with the timestep ($dt$) and the second invariant of the deviatoric strain rate tensor ($\dot{\varepsilon}_{ii}$), where the value at time step $n$ is $\varepsilon_{ii}^{n} = \varepsilon_{ii}^{n-1} + dt\dot{\varepsilon}_{ii}$.
+
+`melt particle&apos;: Implementation of a plugin in which the particle property is defined as presence of melt above a threshold, which can be set as an input parameter. This property is set to 0 if melt is not present and set to 1 if melt is present.
+
+`pT path&apos;: Implementation of a plugin in which the particle property is defined as the current pressure and temperature at this position. This can be used to generate pressure-temperature paths of material points over time.
+
+`position&apos;: Implementation of a plugin in which the particle property is defined as the current position.
+
+`reference position&apos;: Implementation of a plugin in which the particle property is defined as the current reference position.
+
+`strain rate&apos;: Implementation of a plugin in which the time evolution of strain rate is saved and stored on the particles.
+
+`velocity&apos;: Implementation of a plugin in which the particle property is defined as the recent velocity at this position.
+
+`viscoplastic strain invariants&apos;: A plugin that calculates the finite strain invariant a particle has experienced and assigns it to either the plastic and/or viscous strain field based on whether the material is plastically yielding, or the total strain field used in the visco plastic material model. The implementation of this property is equivalent to the implementation for compositional fields that is located in the plugin in \texttt{benchmarks/buiter\_et\_al\_2008\_jgr/plugin/},and is effectively the same as what the visco plastic material model uses for compositional fields.

+Lower limit for particle number per cell. This limit is useful for adaptive meshes to prevent fine cells from being empty of particles. It will be checked and enforced after mesh refinement and after particle movement. If there are \texttt{n\_number\_of\_particles} $&lt;$ \texttt{min\_particles\_per\_cell} particles in one cell then \texttt{min\_particles\_per\_cell} - \texttt{n\_number\_of\_particles} particles are generated and randomly placed in this cell. If the particles carry properties the individual property plugins control how the properties of the new particles are initialized.

+Select one of the following models:
+
+`ascii file&apos;: Generates a distribution of particles from coordinates specified in an Ascii data file. The file format is a simple text file, with as many columns as spatial dimensions and as many lines as particles to be generated. Initial comment lines starting with `#&apos; will be discarded. Note that this plugin always generates as many particles as there are coordinates in the data file, the ``Particles/Number of particles&apos;&apos; parameter has no effect on this plugin. All of the values that define this generator are read from a section ``Particles/Generator/Ascii file&apos;&apos; in the input file, see Section~\ref{parameters:Particles/Generator/Ascii_20file}.
+
+`probability density function&apos;: Generate a random distribution of particles over the entire simulation domain. The probability density is prescribed in the form of a user-prescribed function. The format of this function follows the syntax understood by the muparser library, see {ref}\`sec:run-aspect:parameters-overview:muparser-format\`. The return value of the function is always checked to be a non-negative probability density but it can be zero in parts of the domain.
+
+`quadrature points&apos;: Generates particles at the quadrature points of each active cell of the triangulation. Here, Gauss quadrature of degree (velocity\_degree + 1), is used similarly to the assembly of Stokes matrix.
+
+`random uniform&apos;: Generates a random uniform distribution of particles over the entire simulation domain.
+
+`reference cell&apos;: Generates a uniform distribution of particles per cell and spatial direction in the unit cell and transforms each of the particles back to real region in the model domain. Uniform here means the particles will be generated with an equal spacing in each spatial dimension.
+
+`uniform box&apos;: Generate a uniform distribution of particles over a rectangular domain in 2d or 3d. Uniform here means the particles will be generated with an equal spacing in each spatial dimension. Note that in order to produce a regular distribution the number of generated particles might not exactly match the one specified in the input file.
+
+`uniform radial&apos;: Generate a uniform distribution of particles over a spherical domain in 2d or 3d. Uniform here means the particles will be generated with an equal spacing in each spherical spatial dimension, i.e., the particles are created at positions that increase linearly with equal spacing in radius, colatitude and longitude around a certain center point. Note that in order to produce a regular distribution the number of generated particles might not exactly match the one specified in the input file.

+Weight that is associated with the computational load of a single particle. The sum of particle weights will be added to the sum of cell weights to determine the partitioning of the mesh if the `repartition&apos; particle load balancing strategy is selected. The optimal weight depends on the used integrator and particle properties. In general for a more expensive integrator and more expensive properties a larger particle weight is recommended. Before adding the weights of particles, each cell already carries a weight of 1000 to account for the cost of field-based computations.

 When stabilizing the Newton matrix, we can encounter situations where the coefficient inside the elliptic (top-left) block becomes negative or zero. This coefficient has the form $1+x$ where $x$ can sometimes be smaller than $-1$. In this case, the top-left block of the matrix is no longer positive definite, and both preconditioners and iterative solvers may fail. To prevent this, the stabilization computes an $\alpha$ so that $1+\alpha x$ is never negative and so that always $0\le \alpha \le 1$.  On the other hand, we also want to stay away from $1+\alpha x=0$, and so modify the choice of $\alpha$ by a factor $c$ between zero and one so that if $c&lt;1$, we are assured that $1+\alpha x&gt;0$, i.e., bounded away from zero. If $c=1$, we allow $1+\alpha x=0$, i.e., an unsafe situation. If $c=0$, then $\alpha$ is always set to zero which guarantees the desired property that $1+\alpha x=1&gt;0$, but at the cost of a diminished convergence rate of the Newton method.

 As explained in the paper that describes ASPECT (Kronbichler, Heister, and Bangerth, 2012, see \cite{kronbichler:etal:2012}) we first try to solve the Stokes system in every time step using a GMRES iteration with a poor but cheap preconditioner. By default, we try whether we can converge the GMRES solver in 200 such iterations before deciding that we need a better preconditioner. This is sufficient for simple problems with variable viscosity and we never need the second phase with the more expensive preconditioner. On the other hand, for more complex problems, and in particular for problems with strongly nonlinear viscosity, the 200 cheap iterations don&apos;t actually do very much good and one might skip this part right away. In that case, this parameter can be set to zero, i.e., we immediately start with the better but more expensive preconditioner.

This means particle numbers per cell can deviate statistically from the integral of the probability density. If false, first determine how many particles each cell should have based on the integral of the density over each of the cells, and then once we know how many particles we want on each cell, choose their locations randomly within each cell.

+(parameters:Particles_202/Allow_20cells_20without_20particles)=
+### __Parameter name:__ Allow cells without particles
+**Default value:** false
+
+**Pattern:** [Bool]
+
+**Documentation:** By default, every cell needs to contain particles to use this interpolator plugin. If this parameter is set to true, cells are allowed to have no particles. In case both the current cell and its neighbors are empty, the interpolator will return 0 for the current cell&rsquo;s properties.
+
+(parameters:Particles_202/Integration_20scheme)=
+### __Parameter name:__ Integration scheme
+**Default value:** rk2
+
+**Pattern:** [Selection euler|rk2|rk4 ]
+
+**Documentation:** This parameter is used to decide which method to use to solve the equation that describes the position of particles, i.e., $\frac{d}{dt}\mathbf x_k(t) = \mathbf u(\mathbf x_k(t),t)$, where $k$ is an index that runs over all particles, and $\mathbf u(\mathbf x,t)$ is the velocity field that results from the Stokes equations.
+
+In practice, the exact velocity $\mathbf u(\mathbf x,t)$ is of course not available, but only a numerical approximation $\mathbf u_h(\mathbf x,t)$. Furthermore, this approximation is only available at discrete time steps, $\mathbf u^n(\mathbf x)=\mathbf u(\mathbf x,t^n)$, and these need to be interpolated between time steps if the integrator for the equation above requires an evaluation at time points between the discrete time steps. If we denote this interpolation in time by $\tilde{\mathbf u}_h(\mathbf x,t)$ where $\tilde{\mathbf u}_h(\mathbf x,t^n)=\mathbf u^n(\mathbf x)$, then the equation the differential equation solver really tries to solve is $\frac{d}{dt}\tilde{\mathbf x}_k(t) =  \tilde{\mathbf u}_h(\mathbf x_k(t),t)$.
+
+As a consequence of these considerations, if you try to assess convergence properties of an ODE integrator -- for example to verify that the RK4 integrator converges with fourth order --, it is important to recall that the integrator may not solve the equation you think it solves. If, for example, we call the numerical solution of the ODE $\tilde{\mathbf x}_{k,h}(t)$, then the error will typically satisfy a relationship like \[  \| \tilde{\mathbf x}_k(T) - \tilde{\mathbf x}_{k,h}(T) \|  \le  C(T) \Delta t^p\] where $\Delta t$ is the time step and $p$ the convergence order of the method, and $C(T)$ is a (generally unknown) constant that depends on the end time $T$ at which one compares the solutions. On the other hand, an analytically computed trajectory would likely use the *exact* velocity, and one may be tempted to compute $\| \mathbf x_k(T) - \tilde{\mathbf x}_{k,h}(T) \|$, but this quantity will, in the best case, only satisfy an estimate of the form \[  \| \mathbf x_k(T) - \tilde{\mathbf x}_{k,h}(T) \|  \le  C_1(T) \Delta t^p  + C_2(T) \| \mathbf u-\mathbf u_h \|  + C_3(T) \| \mathbf u_h-\tilde{\mathbf u}_h \|\] with appropriately chosen norms for the second and third term. These second and third terms typically converge to zero at relatively low rates (compared to the order $p$ of the integrator, which can often be chosen relatively high) in the mesh size $h$ and the time step size $\\Delta t$, limiting the overall accuracy of the ODE integrator.
+
+Select one of the following models:
+
+&lsquo;euler&rsquo;: Explicit Euler scheme integrator, where $y_{n+1} = y_n + \Delta t \, v(y_n)$. This requires only one integration substep per timestep.

+
+**Pattern:** [Selection bilinear least squares|cell average|distance weighted average|harmonic average|nearest neighbor|quadratic least squares ]
+
+**Documentation:** Select one of the following models:
+
+&lsquo;bilinear least squares&rsquo;: Uses linear least squares to obtain the slopes and center of a 2d or 3d plane from the particle positions and a particular property value on those particles. Interpolate this property onto a vector of points. If the limiter is enabled then it will ensure the interpolated properties do not exceed the range of the minimum and maximum of the values of the property on the particles. Note that deal.II must be configured with BLAS and LAPACK to support this operation.
+
+&lsquo;cell average&rsquo;: Return the arithmetic average of all particle properties in the given cell, or in the neighboring cells if the given cell is empty. In case the neighboring cells are also empty, and &rsquo;Allow cells without particles&rsquo; is set to true, the interpolator returns 0. Otherwise, an exception is thrown.
+
+&lsquo;distance weighted average&rsquo;: Interpolates particle properties onto a vector of points using a distance weighed averaging method.
+
+&lsquo;harmonic average&rsquo;: Return the harmonic average of all particle properties in the given cell. If the cell contains no particles, return the harmonic average of the properties in the neighboring cells. In case the neighboring cells are also empty, and &rsquo;Allow cells without particles&rsquo; is set to true, the interpolator returns 0. Otherwise, an exception is thrown.
+
+&lsquo;nearest neighbor&rsquo;: Return the properties of the nearest neighboring particle in the current cell, or nearest particle in nearest neighboring cell if current cell is empty. In case the neighboring cells are also empty, and &rsquo;Allow cells without particles&rsquo; is set to true, the interpolator returns 0. Otherwise, an exception is thrown.

+
+**Documentation:** A comma separated list of particle properties that should be tracked. By default none is selected, which means only position, velocity and id of the particles are output.
+
+The following properties are available:
+
+&lsquo;composition&rsquo;: Implementation of a plugin in which the particle property is defined by the compositional fields in the model. This can be used to track solid compositionevolution over time.
+
+&lsquo;cpo bingham average&rsquo;: This is a particle property plugin which computes the Bingham average for the Crystal Preferred Orientation particle property plugin so that it can be visualized.
+
+&lsquo;cpo elastic tensor&rsquo;: A plugin in which the particle property tensor is defined as the Voigt average of the elastic tensors of the minerals in the textured rock.Currently only Olivine and Enstatite are supported.
+
+&lsquo;crystal preferred orientation&rsquo;: WARNING: all the CPO plugins are a work in progress and not ready for production use yet. See https://github.com/geodynamics/aspect/issues/3885 for current status and alternatives. The plugin manages and computes the evolution of Lattice/Crystal Preferred Orientations (LPO/CPO) on particles. Each ASPECT particle can be assigned many grains. Each grain is assigned a size and a orientation matrix. This allows for CPO evolution tracking with polycrystalline kinematic CrystalPreferredOrientation evolution models such as D-Rex (Kaminski and Ribe, 2001; Kaminski et al., 2004).
+
+&lsquo;elastic stress&rsquo;: A plugin in which the particle property tensor is defined as the total elastic stress a particle has accumulated. See the viscoelastic material model documentation for more detailed information.
+
+&lsquo;elastic tensor decomposition&rsquo;: A plugin which decomposes the elastic tensor into different approximations (Isotropic, Hexagonal, Tetragonal, Orthorhombic, Monoclinic and Triclinic) and provides the eigenvectors of the tensor.
+
+&lsquo;function&rsquo;: Implementation of a model in which the particle property is set by evaluating an explicit function at the initial position of each particle. The function is defined in the parameters in section &ldquo;Particles|Function&rdquo;. The format of these functions follows the syntax understood by the muparser library, see {ref}`sec:run-aspect:parameters-overview:muparser-format`.
+
+&lsquo;grain size&rsquo;: A plugin in which the particle property is defined as the evolving grain size of a particle. See the grain_size material model documentation for more detailed information.
+
+&lsquo;initial composition&rsquo;: Implementation of a plugin in which the particle property is given as the initial composition at the particle&rsquo;s initial position. The particle gets as many properties as there are compositional fields.
+
+&lsquo;initial position&rsquo;: Implementation of a plugin in which the particle property is given as the initial position of the particle. This property is vector-valued with as many components as there are space dimensions. In practice, it is often most useful to only visualize one of the components of this vector, or the magnitude of the vector. For example, in a spherical mantle simulation, the magnitude of this property equals the starting radius of a particle, and is thereby indicative of which part of the mantle a particle comes from.
+
+&lsquo;integrated strain&rsquo;: A plugin in which the particle property tensor is defined as the deformation gradient tensor $\mathbf F$ this particle has experienced. $\mathbf F$ can be polar-decomposed into the left stretching tensor $\mathbf L$ (the finite strain we are interested in), and the rotation tensor $\mathbf Q$. See the corresponding cookbook in the manual for more detailed information.
+
+&lsquo;integrated strain invariant&rsquo;: A plugin in which the particle property is defined as the finite strain invariant ($\varepsilon_{ii}$). This property is calculated with the timestep ($dt$) and the second invariant of the deviatoric strain rate tensor ($\dot{\varepsilon}_{ii}$), where the value at time step $n$ is $\varepsilon_{ii}^{n} = \varepsilon_{ii}^{n-1} + dt\dot{\varepsilon}_{ii}$.
+
+&lsquo;melt particle&rsquo;: Implementation of a plugin in which the particle property is defined as presence of melt above a threshold, which can be set as an input parameter. This property is set to 0 if melt is not present and set to 1 if melt is present.
+
+&lsquo;pT path&rsquo;: Implementation of a plugin in which the particle property is defined as the current pressure and temperature at this position. This can be used to generate pressure-temperature paths of material points over time.
+
+&lsquo;position&rsquo;: Implementation of a plugin in which the particle property is defined as the current position.
+
+&lsquo;reference position&rsquo;: Implementation of a plugin in which the particle property is defined as the current reference position.
+
+&lsquo;strain rate&rsquo;: Implementation of a plugin in which the time evolution of strain rate is saved and stored on the particles.
+
+&lsquo;velocity&rsquo;: Implementation of a plugin in which the particle property is defined as the recent velocity at this position.
+
+&lsquo;viscoplastic strain invariants&rsquo;: A plugin that calculates the finite strain invariant a particle has experienced and assigns it to either the plastic and/or viscous strain field based on whether the material is plastically yielding, or the total strain field used in the visco plastic material model. The implementation of this property is equivalent to the implementation for compositional fields that is located in the plugin in `benchmarks/buiter\_et\_al\_2008\_jgr/plugin/`,and is effectively the same as what the visco plastic material model uses for compositional fields.

It will be checked and enforced after mesh refinement and after particle movement. If there are `n\_number\_of\_particles` $<$ `min\_particles\_per\_cell` particles in one cell then `min\_particles\_per\_cell` - `n\_number\_of\_particles` particles are generated and randomly placed in this cell. If the particles carry properties the individual property plugins control how the properties of the new particles are initialized.

The file format is a simple text file, with as many columns as spatial dimensions and as many lines as particles to be generated. Initial comment lines starting with &lsquo;#&rsquo; will be discarded. Note that this plugin always generates as many particles as there are coordinates in the data file, the &ldquo;Particles/Number of particles&rdquo; parameter has no effect on this plugin. All of the values that define this generator are read from a section &ldquo;Particles/Generator/Ascii file&rdquo; in the input file, see {ref}`parameters:Particles/Generator/Ascii_20file`.
+
+&lsquo;probability density function&rsquo;: Generate a random distribution of particles over the entire simulation domain. The probability density is prescribed in the form of a user-prescribed function. The format of this function follows the syntax understood by the muparser library, see {ref}`sec:run-aspect:parameters-overview:muparser-format`. The return value of the function is always checked to be a non-negative probability density but it can be zero in parts of the domain.
+
+&lsquo;quadrature points&rsquo;: Generates particles at the quadrature points of each active cell of the triangulation. Here, Gauss quadrature of degree (velocity\_degree + 1), is used similarly to the assembly of Stokes matrix.
+
+&lsquo;random uniform&rsquo;: Generates a random uniform distribution of particles over the entire simulation domain.
+
+&lsquo;reference cell&rsquo;: Generates a uniform distribution of particles per cell and spatial direction in the unit cell and transforms each of the particles back to real region in the model domain. Uniform here means the particles will be generated with an equal spacing in each spatial dimension.
+
+&lsquo;uniform box&rsquo;: Generate a uniform distribution of particles over a rectangular domain in 2d or 3d. Uniform here means the particles will be generated with an equal spacing in each spatial dimension. Note that in order to produce a regular distribution the number of generated particles might not exactly match the one specified in the input file.
+
+&lsquo;uniform radial&rsquo;: Generate a uniform distribution of particles over a spherical domain in 2d or 3d. Uniform here means the particles will be generated with an equal spacing in each spherical spatial dimension, i.e., the particles are created at positions that increase linearly with equal spacing in radius, colatitude and longitude around a certain center point. Note that in order to produce a regular distribution the number of generated particles might not exactly match the one specified in the input file.

+
+**Documentation:** Weight that is associated with the computational load of a single particle. The sum of particle weights will be added to the sum of cell weights to determine the partitioning of the mesh if the &lsquo;repartition&rsquo; particle load balancing strategy is selected. The optimal weight depends on the used integrator and particle properties. In general for a more expensive integrator and more expensive properties a larger particle weight is recommended. Before adding the weights of particles, each cell already carries a weight of 1000 to account for the cost of field-based computations.

By default, the names of variables at which the function will be evaluated are &lsquo;x&rsquo; (in 1d), &lsquo;x,y&rsquo; (in 2d) or &lsquo;x,y,z&rsquo; (in 3d) for spatial coordinates and &lsquo;t&rsquo; for time. You can then use these variable names in your function expression and they will be replaced by the values of these variables at which the function is currently evaluated. However, you can also choose a different set of names for the independent variables at which to evaluate your function expression. For example, if you work in spherical coordinates, you may wish to set this input parameter to &lsquo;r,phi,theta,t&rsquo; and then use these variable names in your function expression.

 **Documentation:** The kind of scheme used to resolve the nonlinearity in the system. &lsquo;single Advection, single Stokes&rsquo; means that no nonlinear iterations are done, and the temperature, compositional fields and Stokes equations are solved exactly once per time step, one after the other. The &lsquo;iterated Advection and Stokes&rsquo; scheme iterates this decoupled approach by alternating the solution of the temperature, composition and Stokes systems. The &lsquo;single Advection, iterated Stokes&rsquo; scheme solves the temperature and composition equation once at the beginning of each time step and then iterates out the solution of the Stokes equation. The &lsquo;no Advection, iterated Stokes&rsquo; scheme only solves the Stokes system, iterating out the solution, and ignores compositions and the temperature equation (careful, the material model must not depend on the temperature or composition; this is mostly useful for Stokes benchmarks).  The &lsquo;no Advection, single Stokes&rsquo; scheme only solves the Stokes system once per timestep. This is also mostly useful for Stokes benchmarks. The &lsquo;single Advection, no Stokes&rsquo; scheme only solves the temperature and other advection systems once, and instead of solving for the Stokes system, a prescribed velocity and pressure is used. The &lsquo;iterated Advection and Newton Stokes&rsquo; scheme iterates by alternating the solution of the temperature, composition and Stokes equations, using Picard iterations for the temperature and composition, and Newton iterations for the Stokes system. The &lsquo;single Advection, iterated Newton Stokes&rsquo; scheme solves the temperature and composition equations once at the beginning of each time step and then iterates out the solution of the Stokes equation, using Newton iterations for the Stokes system. The &lsquo;iterated Advection and defect correction Stokes&rsquo; scheme iterates by alternating the solution of the temperature, composition and Stokes equations, using Picard iterations for the temperature and composition, and defect correction Picard iterations for the Stokes system. The &lsquo;single Advection, iterated defect correction Stokes&rsquo; scheme solves the temperature and composition equations once at the beginning of each time step and then iterates out the solution of the Stokes equation, using defect correction Picard iterations for the Stokes system. The &lsquo;no Advection, iterated defect correction Stokes&rsquo; scheme solves the temperature and composition equations once at the beginning of each time step and then iterates out the solution of the Stokes equation, using defect correction Picard iterations for the Stokes system. The &lsquo;first timestep only, single Stokes&rsquo; scheme solves the Stokes equations exactly once, at the first time step.
