A Python tool to convert CalculiX .frd files to VTK .vtu files. It is inspired by ccx2paraview https://github.com/calculix/ccx2paraview
This tool converts CalculiX binary .frd files to VTK .vtu files, which can be visualized in tools like ParaView. It supports various element types and can handle multiple files in parallel.
pip install frd2vtufrd2vtu input.frd MIT — see LICENSE.
Tested against CalculiX example FRD files. ❌ indicates an unsupported element type.
