Incidentally, we (myself, Andre Massgin and Mats Larson) discussed a generalization of assembly over interior facets last week that also covers the case of intersections between non-matching meshes.
The central concept in assemble_interior_facets is that of a facet and its two neighboring cells. Our current implementation assumes that this facet is a facets for both cells in the pair. But a generalization would include assembly over triples (facet, cell0, cell1) where facet is contained in the closure of each of the two cells, but it may or may not be a facet for the two cells. It can be part of a facet or part of the interior. If we can implement this (and generate the appropriate code), we would be able to cover quite a few interesting cases (like Nitsche on overlapping non-matching meshes). -- Anders On Wed, Nov 04, 2009 at 11:14:40AM +0100, DOLFIN wrote: > One or more new changesets pushed to the primary dolfin repository. > A short summary of the last three changesets is included below. > > changeset: 7413:4a1d877ec9a4 > tag: tip > user: "Garth N.
