Transfer meshtags to submesh in dolfinx

Hello everyone,

I’m currently trying to solve an equation on only a subdomain. For this, I created a submesh using dolfinx.mesh.create_submesh. This works perfectly, however, I want to transfer the meshtags from the parent mesh to the submesh, to use them for the marking of the measure. Is there a way of achieving this in the current dolfinx version?

Best regards
Max

Are the mesh-tags of cells or facets?

I’m interested in the tags for the facets.
