Hi, First, I would like to congratulate you for developing such a great software.
I tried with version 2.1.0 and the it is able to import with no errors and mesh this surface. This is a surface of a more complex part which I broke down until finding the problematic surface. When I meshed the part, this surface caused a crash of Gmsh and I couldn't retreive the mesh of other surfaces. I would be glad if gmsh presented an error during meshing that surface but still being able to export the mesh of the non-failing surfaces. Then I could correct the mesh using a mesh editor. I know STEP is better than IGES for importing in Gmsh. I also tested several "flavours" of IGES coming from Rhino3d and I found one which is almost as good as STEP. However, I have a part that also produces a similiar error during import like: Error : Something wrong in edge loop Warning : OCC STL triangulation failed using STEP or IGES format with any "flavour". And when I mesh it, Gmsh crashes. Although, as I said I would be more than glad if Gmsh just presented a message of the failing surface and/or not try to mesh these surfaces. This way I could still export the mesh.

Hi Billy - Even on Linux the parametrization of the surface looks weird, and the resulting mesh is extremely distorted. If possible always try to use STEP files instead of IGES (IGES files do not contain the topology, so a geometrical tolerance must be used to decide when entities are identical). > > Regards, > > Billy. > > > -----Original Message----- > From: [EMAIL PROTECTED] on behalf of Billy Araújo > Sent: Thu 7/17/2008 12:35 AM > To: [email protected] > Subject: [Gmsh] Bug in gmsh-2.2.3 / OCC? > > > Hi, > > > I send an IGES file in attachment. > > It gives an error in the edge loop when importing. > > Error : Something wrong in edge loop > Warning : OCC STL triangulation failed > > And when I try to mesh it, Gmsh crashes. > > > Billy. > > > ------------------------------------------------------------------------ > > _______________________________________________ > 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
