Materials

Hi all! For some other project I am working on I took a look at the materials data at src/Mod/Material/StandardMaterial and to the following pages and discussions: http://www.freecadweb.org/wiki/index.php?title=Material http://www.freecadweb.org/wiki/index.php?title=Material_data_model http://forum....

Re: Centrifugal Force Simulation

Hi, just to complete the question, this is my approach (it does not involve FreeCAD, yet):

Re: Why are Neumann BCs mandatory?

we need to check if really a strain and not a fixed was applied (the displacement constraint could be both). ... I need to adapt the pre checks in this regard, done. Would be coold if you guys could give it a try. branch: https://github.com/berndhahnebach/FreeCAD_bhb/commits/femallowstrainconstrain...

Re: Why are Neumann BCs mandatory?

would you give more explanation? I do not really get the point. After some thought maybe I do? If the analysis is valid, why prohibit it, even if the result is trivial? Let me see if I can. FIrst, it is ok to check that there is at least one Dirichlet BC because otherwise the system matrix will be ...

Re: Why are Neumann BCs mandatory?

what would be the problem if only homogenous dirichlet boundary conditions (i.e fixed faces) were given? the displacements would be identically zero throughout the domain, but the problem would be well conditioned nevertheless.

Re: Why are Neumann BCs mandatory?

I think this is a FC limitation. You don't have posted an model. but as far as i can read what's written in the python console it looks like you have add a displacement on a face. FreeCAD says something about displacement at an object... so i'm not sure if what you want at this point is possible......

Why are Neumann BCs mandatory?

Is it a CalculiX restriction?
What if I want to see the stresses when fixing one side of a beam and straining 0.02% the other end in the axis direction?

I get "Static analysis: Neither constraint force nor constraint pressure or a constraint selfweight defined."

Re: Multi-material FEM (i.e. compsolids)

Smooth Bernd!

I was missing the OCC version (I used OCE).
Good work!
