PolyFEM is a polyvalent C++ FEM library.

Compilation

All the C++ dependencies required to build the code are included. It should work on Windows, macOS, and Linux, and it should build out-of-the-box with CMake:

mkdir build
cd build
cmake ..
make -j4

On Linux, zenity is required for the file dialog window to work. On macOS and Windows, the native windows are used directly.

Optional

The formula for higher-order bases is optionally computed at CMake time using an external python script. Consequently, PolyFEM might require a working installation of Python and some additional packages to build correctly:

• numpy and sympy (optional)
• quadpy (optional)

Usage

The main executable, ./PolyFEM_bin, can be called with a GUI or through a command-line interface. Simply run:

./PolyFEM_bin

A more detailed documentation can be found on the website.
