I would like to run the Calculix Cantilever with oofem. ATM I stick with boudary conditions and load. I do not really understand how this works. Some reading is needed. Have you made the cantilever for oofem? Would save me a lot of time ...

Sorry, no I only ran one test case:

to be renamed to concrete_3point.in

[bernd]

great, it helps anyway thanks ... input file runs smooth with oofem and results opens fine in FreeCAD ...

Looks promising.

@Harry:

I changed a lot! Since this is something like a documentation how to add a new solver to FreeCAD FEM, I tried to make some readable commit history. Thus your origin commits changed a lot. I tried to keep as much as possible as the origin. Since this might get into master one day ... Would you have a look and give some feedback if the splitting between your commits and my commits is ok for you?

cheers bernd

Bernd, I didn't do any work on this since October or so. I didn't get far with this and moved on to writing my own solver. So, I will certainly have a look to learn from your work, but I am not worried if this invalidates or overrides my original efforts. Harry
