- Download and install the version best suited to your Operating System (Windows or Linux). It is recommended to install the
mpi
version to get multi-core support (introduced in version 0.21).
- In FreeCAD go to Edit → Preferences → FEM → Elmer
- In the FEM preferences set the correct path for both
ElmerGrid
and ElmerSolver
, or version 0.21 and above: set the path for ElmerSolver_mpi
instead of ElmerSolver
to make Elmer use all available CPU cores.
