I tried the subdivision example provided in libMesh, and I had some questions about the example that I wasn’t able to find an answer to by myself.
In the example (that follows Cirak’s paper from 2000), I see that there are the following steps before the subdivision mesh gets prepared: // Quadrisect the mesh triangles a few times to obtain a // finer mesh. Subdivision surface elements require the // refinement data to be removed afterward. MeshRefinement mesh_refinement(mesh); mesh_refinement.uniformly_refine(3); MeshTools::Modification::flatten(mesh); Here, what’s the exact effect of the mesh refinement? I just tried increasing the refinement to 5 or 6, and the solution started deviating quite a lot (by orders of magnitudes) from the analytical solution. I was just wondering if it’s due to just the nature of subdivision or due to the way libMesh works/handles it? Is there a reason 3 is chosen for refinement?
