I tried to fix this by trying to interpolate the expression onto each Function in the MultiMeshFunction.
from dolfin import * mesh_0 = RectangleMesh(Point(0, 0), Point(1, 1), 16, 16) mesh_1 = RectangleMesh(Point(0.2, 0.1), Point(0.3, 0.5), 20, 20) multimesh = MultiMesh() multimesh.add(mesh_0) multimesh.add(mesh_1) multimesh.build() V = MultiMeshFunctionSpace(multimesh, "Lagrange", 1) v = MultiMeshFunction(V) f = Expression("2") v0 = v.part(0) v0.interpolate(f)
This produces the following error:
------------------------------------------------------------------------- Error: Unable to interpolate function into function space. Reason: Wrong size of vector. Where: This error was encountered inside FunctionSpace.cpp. *** Process: 0
DOLFIN version: 2016.2.0.dev0 Git changeset: 8ea1b4e1a38f15458276d95fe8d751b36c3269b6 *** -------------------------------------------------------------------------
It seems like there is some error in the initialization of _vector for each function and I'm not sure how to fix it.

I've already encountered non-matching multimesh vector dimension here. It seems that this is a design by purpose, not a bug.

Ok, I'm not going to try to fix this issue at the moment, looking forward to having someone fix this issue
