made a hack in the view provider to make all visible just to really proof FreeCAD has them all ... BTW: a BoleanFragment was used instead of a normal Compound. Thus the mesh is conformal !

EDIT: new branch together with mixed mesh analysis ...

udated the branch https://github.com/berndhahnebach/FreeC ... olumeshell

EDIT: new branch together with mixed mesh analysis ...

Is shows all Nodes, all Edges, all Faces and all Faces of Volumes or at least it should show them all. Even lonley nodes and stuff like that ...

Attached a mesh with volumes, faces and edges. It is a BooleanFragment means I assume all topology is glued together in the mesh. Means all topology has shared nodes on the connection points in the mesh. We really need to attract the mixed inp-writer.

Ok, thank you very much Bernd! This hack is a good idea. :D

Currently we compare Code_Aster and FreeCAD/Calculix to choose which is better for our work.

I have seen quite some improvements from FreeCAD version 0.16 to 0.17 in the FEM module. I think freeCAD 0.17 main focus was integration of many already available tools: Gmsh, NetGen, Calculi... already present in version 0.16 but badly integrated. Hopefully in the future Elmer. Also the solution environment has improved. It is really a great step.

Take a look here for a small round trip on a few things that are new...

The FEM team is doing a superb work.

A year ago I would say that open source simulation would never fly. When I tried the 0.17 version I noticed the progress was very big. Contacts, fluids, .... it's still not official but they are on the right track to start to attract users that will push more development aboard...

I start to believe in what I read in this post: http://numerica.pt/2017/08/23/and-the-race-begins/

Maybe after all there is a chance for the open source software to battle agains proprietary solutions it will take time but it will get there... And in the end we will all benefit.
