Dear all, I'd like to find the maximum eigenvalue from a mixed generalised eigenvalue problem. Has anyone tried this?
I can follow the QG slepc example but I would need to assemble monolithic PETSc matrices.
Is there a way to assemble monolithic PETSc matrices for mixed systems?
Yes. assemble(a, ..., mat_type="aij") Cheers, Lawrence
