Looks like it worked. Now I just need to find a way to the creation of cells done for me and that will be the final step for creating a mesh, and then I can move on to latter steps of solving a PDE on the mesh. There’s probably a function in dolfinx or a python package out there somewhere that connects the points into cells such that they form some specified desired shape (in 2D, I think we want triangles, and in 3D, tetrahedrons).
