The netgen mesh also reports an error but gives at least a result: NETGEN_2D failed on subshape # 2 with error COMPERR_ALGO_FAILED "Problem in Surface mesh generation" The critical part of the shape is where the hole touches the boundary in a single point. The meshing algorithm has to create two triangles that share a common point but not a common edge. However, in some literature about mesh structures this is considered invalid -- called a "non-manifold vertex". So maybe, this could be the reason why Mefisto doesn't return anything. And when you zoom-in deep enough into the mesh that netgen generates you will see that there is a little gap. |
