Ambit v1.3

First Ambit release supporting all multi-physics (also monolithic FSI) with latest dolfinx development version

Some new features, such as constraints for fluid and ALE fluid dynamics

Ambit v1.2.9

• Make code compatible with latest dolfinx release and development version
• Still keep option to use old mixed dolfinx branch, since all functionality of it has not yet been fully transferred
• Option for spatial expression in Robin valve viscosity
• Minor fixes

Ambit v1.2.8

• Fix linearization of ALE w.r.t. fluid velocity in monolithic FSI / FrSI with strong Dirichlet conditions from fluid on ALE
• Options to scale ALE stiffness dependent on element quality
• Minor improvements

Ambit v1.2.7

• Option to have n instead of one model of 0D 2- and 4-element Windkessels
• Option to set a Dirichlet profile from a file and ramp it via a time curve
• Several smaller fixes

Ambit v1.2.6

• Several smaller fixes
• Feature of using a file in Dirichlet BCs (e.g. when prescribing a pre-computed profile)

Ambit v1.2.5

Fixes:

• Simultaneous time-controlled Dirichlet and Neumann conditions using old state (e.g. for mid-point time scheme) were wrong due to false access of old time curve values
• Periodic reference state estimation of solid-flow0d problem
• Restart of Frank-Starling models
• FrSI prestressing
• Several other minor fixes

Features:

• Allow user to pass PETSc options to preconditioner
• Support for latest dolfinx (not yet for mixed branch, e.g. FSI or valves/immersed fluid surfaces)
• Spatial expressions in Neumann loads
• Crossfiber active stress models

Ambit v1.2.4
