Hello, are there any new possibilities for this problem using the new OpenCascade-options? Or is there any option to specify the layers of an extrusion by surface meshes?

Afterwards, I want to mesh the model with gmsh and in a third step assign the created mesh to the existing geometry. Is there any way to create a (semi-)structured mesh using volumes already defined in my geo-file?

I tried a lot of solver options but even with the frontal algorithm and AllHexas subdivision algorithm I cannot get a proper mesh. Volume elements are only created for the left and right volume while the boundary surfaces of the middle volume are meshed but no volumes are created and different errors are thrown by gmsh, e.g. "Cannot use frontal 3D algorithm with quadrangles on boundary" for frontal 3D Is there any way that I am missing? Do I somehow have to mesh the middle volume first? Best regards Martin Rädel ------------------------ Deutsches Zentrum für Luft- und Raumfahrt e.V.
