WebDec 31, 2024 · An update: there’s a difference between using gmsh 2.7.1 and 4.7.1. It looks like it’s almost working in 4.7.1 (i.e. uploading the mesh into freefem and asking for its labels returns 3 labels). On the other hand, what should be a hole in the mesh is now meshed, too. WebJan 15, 2003 · Many thanks, > cf. tutorial/t5.geo The easiest way to generate such geometries is to use the GUI : to define a volume, you first select the exterior boundary, then gmsh will ask you to select the boundary of any holes in the volume. Beware that the boundary of the hole must be disjoint from the exterior boundary.
