Thanks Let me simplify my question here for someone to answer it later.
In short, I want to import a mesh and a CAD file, set the CAD's manifold to mesh, and refine mesh according to CAD's geometry like step-54 but in 3-dimensional. For example, a sphere shell. 1. What's the best CAD and MESH software to generate the files for deal.ii to read and *process*? I hope boundary tags on internal faces are kept. COMSOL, GMSH, Cubit, etc. 2. How to adapt the code in step-54? My IGES file gives more than one shell and wires. 在2022年10月17日星期一 UTC+8 21:49:46<Wolfgang Bangerth> 写道： > On 10/17/22 00:09, 'yy.wayne' via deal.II User Group wrote: > > > > So for a imported geometry one has to manually set these properties to > > corresponding faces and lines?
