A new release version of the PrePoMax contains the following FEM features:
And the following user features:
The defeaturing capability uses the OpenCascade function exposed through the Gmsh API. The feature is described in 3D Model Defeaturing - Forum Open Cascade Technology
Its integration is very basic, and after every defeature command, the old geometry is replaced by the new one without the option to go back a step.
Great. FreeCAD also has this tool and it’s surprisingly powerful: FEM Geometry Preparation and Meshing - FreeCAD Documentation
This is a really amazing feature! Thank you!
Wow ! Thanks @Matej
Now I just need a cutting/splitting (plane) tool - No pressure 
it’s a great and amazing when seeing basic CAD operation inside PrePoMax, maybe boolean operation and solid partition is possible in the future.
This is amazing.
Thanks a lot. It would be really helpful to have this tool.
As @synt already mentioned, it would be great to have a splitting tool and may be a bit easy approach than transfinite or extrude/revolve operation to create structured hex mesh
Hello!
It seems the download is out of order…
Maybe is the server down?
