Partition creation of 3D mesh

[bilenemek]

If you prefer graphical user interface, try to use Gmsh in FreeCAD, there is a direct mesh export for FEniCS functionality.

Another method is Salome by using for example NetGen inside, export med and then convert to FEniCS, have a look in this post for more details on this:

Best strategy for importing external meshes

One method, which I am using extensively, is Salome export as med to gmsh to xml to h5. You need to install Salome and import CAD or generate your CAD file in there. By using Salome you can also select and give names to boundaries. Then after exporting, in FEniCS you see these names as numbers. Have a look at Back Matter in this book https://link.springer.com/book/10.1007%2F978-981-10-2444-3 in Appendix A.3 Complicated Geometries in FEniCS For any specific step, you find difficult, simply as…
