Yes, it was requested a few times.

> Dear All, It’s possible to create path and linearize the stress along the path in order to extract Membrane and Bending contribution as requested by ASME VIII Div.2 Part 5 or EN13445-3 Direct Route (Annex B)? Thanks Michele

> Hi guys, Foremost, thank you so much for this software. It has a clear, straight forward GUI, works nice with SALOME, and in each version gets more and more sophisticated. I have two questions: I do a lot of study with temperature dependent material values in pressure vessel engineering. When I define a material in PPM, there is option for “temperature dependent data points” for thermal expansion but not for thermal conductivity. Is this missing because of some limitation of Calculix, or it…

For now, it can be done in FreeCAD FEM.
