| Task | Software | Status | | :--- | :--- | :--- | | CAD | FreeCAD 0.21+ (with Realthunder branch) | Excellent – Parametric modeling works. | | Assembly | Ondsel (based on FreeCAD) | Good – Assembly 4 workbench is stable. | | Meshing | Gmsh or Salome | Native & Fast – Direct Linux I/O. | | Simulation | OpenFOAM (CFD) / CalculiX (FEA) | Industry Standard – Outperforms Windows by 15-20%. | | Post-Processing | Paraview | Best-in-class – Native Linux GPU rendering. | Company: HydroFlow Dynamics (5 engineers

Verdict: Fully functional for small-to-medium mechanical parts, thermal analysis, and aerodynamics. Not suitable for complex surface modeling (auto/aero).
