I have run PETSc example ex42.c using the ex42-fsschur.opts options without error. However, if I try to use ex42-mgfs.opts, ex42-mgfs2.opts, or ex42-mgschur.opts, I get the error
PETSC ERROR: Arguments are incompatible PETSC ERROR: MatPtAP requires A, mpiaij, to be compatible with P, mpimaij Do you have any suggestions what might cause this error?
