Dear Mr. Geuzaine, Thanks a lot for the advice! Without the -saveall argument, everything works fine.

Weird... The "before.msh"/"after.msh" files are created for debugging purposes in the triangle->quad recombination algorithm, when the "-saveall" option is used. (This will be removed in a future version.) What happens if you run Gmsh (without Python), directly from the command line, e.g. gmsh myfile.geo -2 > Thanks in advance! > > Best regards > Andreas > > —————————————————————————— > Deutsches Zentrum für Luft- und Raumfahrt e.V.
