Welcome to the FEMuS project! FEMuS is an open-source Finite Element C++ library built on top of PETSc, which allows scientists to build and solve multiphysics problems with multigrid and domain decomposition techniques.
-
Clone the FEMuS source code from the github repository:
git clone https://github.com/FeMTTU/femus.git
-
You need PETSc for FEMuS to work. If PETSc is not already installed in your machine, the script "install_petsc.sh" in contrib/scripts/ will install it automatically, with the following syntax:
./femus/contrib/scripts/install_petsc.sh --prefix-external my_dir
where "my_dir" is the path of the directory, either absolute or relative, that will contain the PETSc folder (please put it outside of the femus repo directory, to prevent from potential git tracking).
-
Source the "configure_femus.sh" script and execute the function "fm_set_femus" in order to set some environment variables:
source femus/contrib/scripts/configure_femus.sh
fm_set_femus --prefix-external my_dir --method-petsc opt
-
Create the build directory, cd to it and run cmake:
mkdir femus_build
cd femus_build
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE="[Debug Release RelWithDebInfo MinSizeRel None]" ../femus
-
Finally, type
make -j $((
nproc- 1))
to compile the library with all applications.
