Hello. Yes, optimizing is generally a good idea for practical finite element work (though I didn't do it in the last posted example - it wasn't necessary to get a workable mesh from quadcan1.geo in my Gmsh 2.8.4). Optimizing is available in the GUI, as mentioned, or via the command-line options, "-optimize" or "-optimize_netgen". http://geuz.org/gmsh/doc/texinfo/gmsh.html#Command_002dline-options Maybe they're only for tetrahedra though. I'm not sure whether they'll do anything for a plane triangulation. I see there's also a "-optimize_lloyd" ("Optimize 2D meshes using Lloyd algorithm"). I can't test here whether these fix the problem as I can't reproduce the original error message on 2.8.4. I see that the latest stable is 2.9.3 so I should probably update myself. _______________________________________________ gmsh mailing list [email protected] http://www.geuz.org/mailman/listinfo/gmsh
