This is the proximate error. Your definition from Patrick has: class FixHermiteDerivativeValue(DirichletBC): @utils.cached_property def nodes(self): if V.mesh().mpi_comm().size > 1: raise NotImplementedError return [1] # the derivative component of the left endpoint I think it might work if you use from pyop2.datatypes import IntType and then return numpy.asarray([1], dtype=IntType) Thanks, Lawrence
