[X] I checked the documentation.
Issue
Trying a FEM-eigenvalues-analysis of a cantilever-beam on osx-arm64 didn't work out as I expected. FreeCAD showed a messed up beam-mesh. FreeCAD uses calculix as FEM-analysis-tool. As I expected that something is wrong with the cross-compilation I compiled calculix directly on osx-arm64. But the error was still there. Calculix uses arpack for computing the eigenvalues. So the next thing I tried waas switching between the different builds of arpack (nompi, mpipich, ...). But none of these worked.
