I’ve just started to learn CalculiX with Gmsh, but it doesnt really work. I opened a simple beam (step-file) with Gmsh and converted it to geo-file by Creating a physical group (Volume). Then I created a 2D-mesh. After that I exported it to an inp-file for reading it with CalculiX Launcher. Finally I converted it to inp-File for Python-script with the launcher. But if I run the CGX-Preprocessor an empty cgx appears. Did I do anything wrong?
