I have a bounding box with several curved cylinders in it. The cylinders have two layers and bridges. I tried to mesh them. The first time without error. But failed to do FEM analysis on Elmer. When remeshing it second time, it returns error, saying stop meshing since boundary mesh is overlapping. Please find my files in the following link. Any hints will be appreciated. Thank you very much!
