In this forum thread: [general] about the future of the FEM workbench - FreeCAD Forum some FreeCAD devs and FreeCAD FEM community members discuss where they see the FEM workbench improving. There is a bunch of CalculiX related discussion (along with Elmer). I thought it may be of interest for folks in this CalculiX forum to know about + perhaps jump in and participate.
Happy cross-pollinating!
