It's now too late to edit my question, but I already realized that the size
and location difference between the geometry and mesh is because I didn't
scale the geometry by 0.001 as is done in the tutorial. And I know you can
generate an initial mesh from gmsh or another tool.
My final questions ar
Dear Daniel,
