Is it possible to use code aster as a solver with the model we created in Prepomax? Is there a tutorial? I need help ---

No, Code\_Aster has a completely different (and much worse in terms of readability) syntax. But there is an initiative to add Code\_Aster support to FreeCAD FEM, at least for shells including composites: [Code Aster integration into FEM workbench by TimSwait-AMRC · Pull Request #28380 · FreeCAD/FreeCAD · GitHub](https://github.com/FreeCAD/FreeCAD/pull/28380) ---

1 CA needs med models. Ppm makes inp models. Use meshio to convert inp into med. 2 Solve with CA. 3 Use meshio to convert result med into vtk. Then use Paraview to view vtk. Or There is vtk2frd maybe. Then you can open frd with ppm. ---

It would be best if there was also a converter from .inp model and analysis definition to CA format. I haven’t found one on GitHub yet, but who knows, maybe someone will make it. Nowadays, it’s not a big issue to generate a Python tool like that. ---

i succesful to convert .inp to .med. I think not a simple as a convert .inp to. med and solve with CA. We must make .comm and other. It’s complicated 😀 ---

I wrote one (ppx2aster.py) a while ago, handles linear statics & dynamics from PrePoMax \*.inp. It was a nightmare to write coz CA syntax and re-inventing wheels. I’ll add to my TODO to review my code from back then, it worked for complex assemblies too, unlike CCX solver. When I get the time/energy I’ll put it up on GitHub. Other comments here: The issue is never to translate meshes, that’s easy, but to translate complete setups. meshio is old and didn’t really do the job proper. It has now been renamed into [meshlane](https://github.com/simvia-tech/meshlane), and supported by [Simvia (EDF sub)](https://simvia.tech/software/code-aster). Check them out for all things code\_aster. ---

maybe you can share about your program on github, i curious try your py. program ---

OK, I’ll do it next week. Unfortunately, coz of code\_aster ways, I can’t just drop the py here, it’d make little sense without notes and examples I did, which I’ll add to the repo with some how-tos. Deal!
