Geometry loaded from IGES File is incorrect and cause a crash in meshing
flanged_pipe.igsI created an IGES file using Open Cascade (attached). The file load properly but the half-sperical surface appears incorrect. You can see it by clicking Geometry/Physical Groups/Add/Surface, there is a hole in in the surface.
When I try to mesh the part, the application crashes.
I tried opening the same file in CATIA V5 and the geometry appears correctly.
