Hi Jonas - The problem comes from the STL import: since there is no connectivity in STL files, Gmsh has to use a geometrical tolerance to determine when vertices are identical. The default tolerance is a bit to large in your case, resulting in nodes being merged that shouldn't have been. Add Geometry.Tolerance = 1.e-12; at the begining of your .geo file: it will decrease the tolerance and should fix the problem. > > kind regards > jonas biehler > > > > On Thu 19/06/08 6:12 PM , Christophe Geuzaine [EMAIL PROTECTED] sent: >> [EMAIL PROTECTED] wrote: >>> Hi there, >>> i am currently using gmsh to create 3d volume meshes >> from an stl file, which describes the surface.
