Zitat von andrew <[email protected]>:
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 a topology is called a CompSolid in OpenCascade. Since I have no
experience with the new GMSH functionallity I normally use FreeCAD to
create such topology and use brep (The native OpenCascade format) to
exchange the topology with GMSH.
