This is correct. > However, I am also wondering if there is a way to set the interior_parent > in a more "automatic" way?

I'm afraid there's currently no avoiding this requirement on your initial meshes. We should now be correctly setting interior_parent after mesh refinement and ParallelMesh redistribution, but the initial data comes from you. > Will this be automated such that when a method like > *prepare_for_use* is called the interior parents will also be set? Hmm... That wasn't on my todo list, and it would be a big change, but it's at least possible in principle, assuming the user shares nodes between the two elements in a consistent way. And it really needs to be on my todo list, doesn't it? Otherwise we're not likely to handle restarts on mixed dimensional meshes properly without manual intervention. I don't know how many weeks (months?) it'll take before this works its way to the *top* of the list, though, so if you want to take first crack don't wait for me. > Given there is some complications if an element has the possibility > of having more than one interior parent (like the example mesh in > tests/mesh/mixed_dim_mesh_test.C). Hopefully we now (as of this summer) handle that case appropriately: when library code needs to look at *all* an element's corresponding interior elements, it doesn't just query interior_parent() and stop, it uses find_interior_neighbors() to get the whole set. --- Roy ------------------------------------------------------------------------------ Monitor Your Dynamic Infrastructure at Any Scale With Datadog!
