Avoid PETSc segfaults due to DMCollection #468

Closed sblauth closed 4 months ago

sblauth commented 4 months ago

The PETScDMCollection can still be used with newer versions of PETSc / petsc4py. However, using .createVecs or similar cannot be done on the transfer matrix. The matrix can, however, still be multiplied, which is all we need.

Note: Some tests will fail - this is due to the fact that we merge this onto v2.1.3.
