Tim: I'm not sure I understand your question, but in short: A mesh is a good initial mesh for a curved geometry if it adequately resolves the curvature of the surface you want to mesh. For example, if the surface oscillates with a vertical deformation like sin(2*pi*x/lambda) then you can't

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

[deal.II] Step-54 Initial mesh

2024-08-14 Thread Tim Braun
Hello, Forgive me if I missed something obvious.I'm having trouble understanding the function of the initial mesh file and how to create one that is suitable for a custom NURBS geometry. It looks like the mesh file in the Step-54 tutorial contains two facets that are very small compared to the
