Disabling OpenCascade CAD healing for small edges seems to fix the problem: use "Geometry.OCCFixSmallEdges=0;" in a script, or "Tools->Geometry->General->Remove small edges..." in the GUI. PS: if possible use STEP files instead of IGES. The geometrical tolerances required by IGES files are an unending source of problems. > Thanks for any hint, > > Olivier Pierard > > > ------------------------------------------------------------------------ > > _______________________________________________ > gmsh mailing list > [email protected] > http://www.geuz.org/mailman/listinfo/gmsh -- Prof. Christophe Geuzaine University of Liege, Electrical Engineering and Computer Science http://www.montefiore.ulg.ac.be/~geuzaine _______________________________________________ gmsh mailing list [email protected] http://www.geuz.org/mailman/listinfo/gmsh
