Re: Plotting results per element
i think averaging integration point per element would be sufficient. This is how most commercial packages do it.For this we would need to plot them in integration points of the FEM element?

Re: Fem constraint contact
So I found the problem although Face index start at 0 the Face numbers on start at 1 Fixed now :D So currently I step through compound and find closest faces for the whole compound Now the question is if I have a face how do I check that the closest face is not part of the same sub solid ? The compo...

Re: Plotting results per element
I have done some updates on the ccxdatfile reader https://github.com/makkemal/FreeCAD/tree/sdv_results_read This was mostly for own use Since Element plots don't exist I did not update other readings functions. Here is some code that changes element volumes to nodal values and assigns it to temperat...

Re: Plotting results per element
How do I get the element numbers and nodes associated from the Resultmesh ?
In the python console to translate it to the element average ?
Thing moved around a bit since I last looked at this
