====== PETSc 3.16.6 ======

Requirement for DAMASK 3.0.0 is a PETSc before 3.20.

If the system python is newer (e.g.3.13) a specific version has to be installed (deprecated module)

<code bash>
python3.12 ./configure --prefix=/opt/apps/libs/petsc-3.16.6  --with-cc=mpicc --with-cxx=mpicxx --with-fc=mpif90
</code>

<code bash>
make PETSC_DIR=/locData/build-petsc3.16.6 PETSC_ARCH=arch-linux-c-debug all
</code>
