Good afternoon,
First, congratulations for the development of Gmsh, this tool has a lot a great qualities. I try to mesh several very thin surfaces, structured in a network of cracks. Two large surfaces are situated on both sides to this network and communicates with it. For large cracks, the mesh is correct (so I think the file .geo is well defined, I can send the source files if needed), but for thinner cracks (40e-6 m compared to a total domain of 10e-2 m for example), I am not able to use a characteristic length in the cracks smaller than their size, Gmsh sends "segmentation fault" due to 3 identical points in qtest and crashes. The options used for meshing surface are plane, MeshAdapt+Delaunay, a very low geometry tolerance is used and other options are standard. I know this case is complicated to mesh, but would advanced options or particular strategies be able to solve this problem? Thank you for your time. David Crevoisier.
