I was trying to learn to simulate in fenicsx the Hele-Shaw flow past a circle based on a tutorial — Fig 1. Hele-Shaw flow past a circle · An album of computational fluid motion . But the tutorial uses older package dolfin, I am trying to recreate in dolfinx (fenicx) but getting error, and unable to u…

You can check that the facets on your circular boundary has not been found: facet_func = dolfinx.mesh.meshtags(mesh_obj, fdim, facets_noflow, np.full_like(facets_noflow, 2, dtype=np.int32)) with dolfinx.io.XDMFFile(mesh_obj.comm, "out_mixed_poisson/mesh.xdmf", "w") as file: file.write_mesh(mes…
