If you have a recent Mac with an Apple silicon (arm64) chip, mind the following:
- Python cannot install the fast MKL Pardiso solver on arm64 natively and will use Accelerate by default, which becomes unacceptably slow for larger problems. There are two workarounds, either install pyoomph in a Rosetta 2 terminal to use MKL Pardiso or install PETSc/SLEPc and use MUMPS as fast linear solver instead.

Rosetta 2 terminal, see here how to set it up (note that recent systems must be handled as described here). Also, please make sure to not upgrade your mkl package, i.e. enforce it to version 2021.4.0.

python3 -m pip install mkl==2021.4.0
