Thank you! Does it work also with STEP data imported from CAD? Matthias > -Ursprüngliche Nachricht- > Von: Christophe Geuzaine [mailto:cgeuza...@ulg.ac.be] > Gesendet: Mittwoch, 3. Mai 2017 10:34 > An: Zenker, Dr. Matthias > Cc: andrew; gmsh@onelab.info > Betreff: Re: [Gmsh] boolean part

Have a look at the new boolean examples, e.g. http://gitlab.onelab.info/gmsh/gmsh/blob/master/demos/boolean/compsolid.geo http://gitlab.onelab.info/gmsh/gmsh/blob/master/demos/boolean/compsolid2.geo BooleanFragments does exactly what you need. > On 3 May 2017, at 10:14, Zenker, Dr. Matthias

Hi, I would also be interested in that functionality. It would resolve the old “duplicated surfaces” problem that forced me (and others) to leave gmsh and do the meshing with Salomé, even though IMHO gmsh does a better job especially in 3D meshing – in Salomé, only netgen is available as 3D alg

This is what I came up with too. I create the geometry and import it to gmsh as brep. The problem I have now is how to assign characteristic lengths in individual groups (edges, surfaces). So far I haven't been able to do that with a result that works correctly. Kind regards Andrew Στις 3 Μαΐ 201

Zitat von andrew : In Salome which uses the opencascade model there is a Boolean operation called partition. With this you can create a solid from two others but with a shared face. A usage of that is the creation of meshes with internal walls in it with zero thickness aka 'baffles'. FYI Such
