Dolfinx: Mesh refinement

[dokken]

@fesolutions

dofs = fem.locate_dofs_topological((V), msh.topology.dim-1, ft.find(2))

Change this to

msh.topology.create_connectivity(msh.topology.dim-1, msh.topology.dim)
dofs = fem.locate_dofs_topological((V), msh.topology.dim-1, ft.find(2))

How to compute entity-to-cell connectivity?

Continuing the discussion from Any guides to implement a material model with softening with DOLFINx?: Hi. Firstly, sorry for the lack of MWE (I am updating @bleyerj’s dolfinx_materials to run with FEniCSx 0.8.x, and creating one will take some time, and it may be that it’s not completely needed). Also, I tried a search: connectivity after:2022-01-01 date, but that didn’t lead anywhere. Mainly, I am getting a RuntimeError: Entity-to-cell connectivity has not been computed. Is anybody familiar…
