Hi, I'm working with Adrian on our PetSc project at the University of Auckland. I think I've found a couple more fortran interfaces that are missing: DMPlexGetFaceFields DMPlexGefFaceGeometry I get the error: Undefined symbols for architecture x86_64: "_dmplexgetfacefields_", referenced from: _rhs_darcy_local.2542 in darcy.o "_dmplexgetfacegeometry_", referenced from: _rhs_darcy_local.2542 in darcy.o I haven't got to the restore stage yet but I think probably these ones are missing too: DMPlexRestoreFaceFields DMPlexRestoreFaceGeometry Also I'm having trouble declaring a pointer to a PetscFVFaceGeom type to use with the DMPlexGetFaceGeometry. Is there a trick to this or maybe its definition in fortran is missing too? Thanks very much!
