Is it possible that you just add my commit "Fix saving values for Infinity and Capacitance BCs" from https://github.com/HoWilgh/FreeCAD/tree ... Cs/src/Mod ??
I am a bit in a hurry and do not get the rebaseing to your master branch right.

Re: List Select Macro (Select hidden sub-objects)

I have updated the code for this macro and it is working in 0.18.4, but when I am in FEM it will not let me select the inner object. I have been trying to follow the tutorial https://www.freecadweb.org/wiki/FEM_Shear_of_a_Composite_Block and I am stuck on selecting the second object for the second ...

Does this run?
95% of it. If this merge is done than I will add point 1+2 and the model/example of the tutorial will be finished.
Point 3 is an extra which is interesting for me.

Re: Elmer electrostatics FEM

Next steps just for documentation: code cleanup and adding test (if capacitance matrix selected in equation than.. add the 'constant' 'Permittivity Of Vacuum' into the equation dialogue add the equation 'Electric Force' and according boundary conditions (see https://www.nic.funet.fi/index/elmer/doc/...

Re: Development of an Optimization workbench

Hi Petrus, Welcome to the forum. I am happy to hear that there is an effort to build an optimization toolbox for FC-FEM. FC would benefit very much from such workbench/toolbox. Since it looks like you what to build it in a very general way, you maybe want to have a look at dakota https://dakota.sand...

Re: Elmer electrostatics FEM

I also have implemented the farfield/electric-infinity boundary condition and the settings for calculating the capacitance matrix. This needs some extra polish which I will be able to do within a few days. The current files can be found attached. I struggle a bit with git and want to use this to doc...
