+1 ... we are on the same road 8-)

Re: feature: general initial value and body source, to be tested

just because we need to present two objects to the user, it does mean we need to implement two objects. Slowly I get an idea. May be we only make one base object, FemConstraintGeneric. All these new constraints are inherited from this. BTW: do you have abetter example than Initial Temperatur? Since ...

Re: feature: general initial value and body source, to be tested

but body source could be a constraint acting on a vertex. For example we could implement the constraint displacement as body source constraint.

Or would this be a generic initial value constraint?

Self weight would be a generic initial value constraint, than?

Re: Development of an Optimization workbench

ATM FreeCAD reads all nodal values in lists and creates colored plots from it. Calculix is able to output the results in integration points too (element results) You mentioned that FreeCAD reads nodal values and creates colored plots. In FreeCAD FEM are two independent post processing systems. Both...
