Hello Prj, I hope you doing well. I currently try to build mesh with a interface face, which I can use it for separating design domain later. However, I find the freefem partitioning with overlapped domain works fine with this .msh file, while the No-overlap partitioning with trunc function gives me some error. I am really running out of the cue. Could you give me some ideas about which part of this code or the mesh is not right? I am attaching the .stp .msh & .edp file here.
Thank you so much.
