Hi Bernd,
can you try with adding the -string "Geometry.OCCSewFaces=1;" option ? This should work with relatively simple geometries, i.e. faces sharing a common line.

Hi there, This is my first post to the mailing list so I may introduce myself first. The "identifier" given to me by my parents is Bernd and this corresponds to what most people call myself. The bred to feed myself an my familiy I earn in an engineering office near Zuerich in Switzerland. I'm structural engineer in the building industry. In my spare time I develop on the FEM Workbench and on the Arch Workbench of the parametric open source cad plattform FreeCAD. This is why I'm gone write to this list. FreeCAD uses for internal parametric surface and solid meshing netgen. AFAIK due to licence incompatibility between FreeCAD and GMSH it has never been an option to use GMSH instead. But there exists a FreeCAD macro which uses the GMSH installed on ones computer for meshing. Most users mainly use this GMSH macro for meshing their models including myself. The macro exports a *.step meshes with GMSH and imports the *.unv mesh back into FreeCAD. Babbled enought,the important part of the post ... I run into trouble with meshing compunds of faces. The faces where not connected to each other and thus a Finite Element Analysis will fail to work without manual connection off all the faces of the compund. As a example a very simple compund of just two faces is taken. mesh command: gmsh compound_of_faces.step -3 -format unv -o compound_of_faces.unv -algo netgen -clmax 100,00 -order 2 -optimize gmsh --version 2.8.5 on Debian Jesie I was wondering if it is possible to tell GMSH to mesh a connected Surface Mesh of a compund of faces?
