Thanks, this has worked. I assumed PETSc would just pick up the HDF5 library I already had on my system but perhaps that requires --with-hdf5-dir=/usr or something similar? Would this HDF5 library need to be configured for MPI as well? The underworld3 test suite is mostly passing but I do get a handful of failures coming from petsc4py.PETSc.SNES.getConvergedReason() giving -3 instead of the expected 0. But that's more a question for underworld devs. Leon
