Mmg3d mesh improvement

Web16 apr. 2024 · The diameter of the cylinder is 600 m. After a first refinement of the mesh with MMG (MMG3DLIB) I get a model in which the elements with minimum dimension are positioned near the terrain (lower part of the volume) and the elements with maximum dimension are positioned in the upper part of the volume (far off the terrain). WebThe line with mmg3d and the command after that won't work because the first command with gmsh is the problem. But maybe the error that I get from mmg is helpful: currently I get "Check that your mesh contains tetrahedra." I think this is because of the missing volume. – May 21, 2024 at 15:13 1 @A.M. have you tried adding some physical ids?
