A 2D electro-mechanical simulator. It can simulate isotropic and anisotropic wave propagation on a 2D domain. SAC is also included. It was developed in CodeLite, but with the help of Jan L. and CMake, the entire program can be build without CodeLite.

Compilation

This project uses CMake to generate cross-platform build configurations. Either use cmake-gui or the terminal from the project folder (where CMakeList is located):

# Create a subfolder (generally called build)
mkdir build
cd build

# Generate a project for the default platform
cmake ..

# Alternatively display the available platforms and generate the project for the platform of your choice
cmake --help    (optional)
cmake .. -G "Xcode"    (example)
cmake .. -G "Unix Makefiles"    (example)
cmake .. -G "Visual Studio 15 2017 Win64"    (example)

# Then use your IDE or use CMake to compile
cmake --build .

How to use

After a successful build, two executables can be found in the build folder. The em2d_cluster is to be used on a cluster, since it does not have any visual dependencies included. It is so to say recommended for parallel calculation on the cluster. The em2d_viewer is instead for the desktop, since it requires freeglut for graphical rendering, which should be used for generating images or videos out of images.

There is a sim_conf.ini file, which should be loaded with

./em2d_viewer --load <path to sim_conf.ini>

./em2d_cluster --load <path to sim_conf.ini>

# a concrete example
./em2d_viewer --load ../sim_conf.ini

since it has basic configuration for further use already. Any modification can be done in this ini-file without need for recompiling. If you start the viewer, the program will present you with some views, like the fields u-value, v-value or the stretch-map.

To initialize a simulation, you can either use the key d for a stimulated "dot", s for a spirale or c for "chaos" or a predefined fibrillation, constisting of several spirals. After pressing any of these keys once, press space to actually start the simulation.

To take a picture, press p. A screengrab will be saved with the current date and time in the filename.

While the simulation runs, you can also just randomly draw with the mouse in the u-field, if you're bored.

Further configurable parameters can be taken from the sim_conf.ini file.
