OpenRadioss FEM: Preprocessing with FreeCAD on Linux

OpenRadioss is a premier open-source solver for complex non-linear dynamic problems. In this video, we demonstrate a complete, end-to-end simulation workflow on Linux using a 100% open-source toolchain, that works for small and medium size models. Using a tension bar as a minimal working example, we walk through the following pipeline: Preprocessing - Geometry creation and meshing (Gmsh) in FreeCAD. Export - Generating the input file in Abaqus format (.inp). Refinement - Manual edits for specific model adoptions. Conversion - Translating the model to OpenRadioss format (.rad) with the OpenRadioss-tool inp2rad. Solving - Running the OpenRadioss starter and engine. Postprocessing - Visualizing the final results in ParaView (results converted to vtk-format by the OpenRadioss-tools anim_to_vtk and th_to_csv). This workflow bridges the gap between CAD design and high-performance crash/impact simulation without proprietary overhead, still it is limited by the manual edits needed. Since this field is evolving fast this video is just a snapshot, we used Ubuntu 24.04, FreeCAD 1.0.2, OpenRadioss latest-20251127. The files used in this tutorial have the DOI 10.5281/zenodo.19053806 und you find them here https://doi.org/10.5281/zenodo.19053805 The conversion scripts, for both input and output files, are located in a subfolder of the OpenRadioss GitHub-repository https://github.com/OpenRadioss/Tools 00:00 - Intro 00:16 - Model and approach 02:33 - FreeCAD preprocessing 05:32 - Manual edits 09:37 - OpenRadioss and postprocessing 13:26 - Outro
