I am a PhD student and am just familiar with FreeCAD. During my research I will be developing algorithm for feature based Midsurface (needed for Shell elements in Thin parts). In 2D the corresponding entity, called Midcurve, is being worked on.
Is there any interest in mentoring-guiding me to get these functionalities in FreeCAD-FEM?
I have already started implementation on Midcurves using few other libraries. You may want to refer to thispaper for some idea.
Overall idea of Midsurface Generation can be found here.
