Import CATIA assembly into Simscale

Hello,

Someone knows how to import an assembly from CATIA to Simscale? I want to work on a CFD simulation and be able to define different mesh settings to different parts. Right now I’m doing it like this: Tools > Generate CAT Part From Product…>Save as > STL.

And then I’m importing it to Simscale but it opens as a single part. Someone has a good method to do this?

Thanks :slight_smile:

Hi @andresuriegas,

could you try the export as a step file? The next step would be uploading the step file to OnShape and exporting it from there as stl.

Tell me if that worked for you. If you need help let me know.

Cheers,

Jousef

@andresuriegas Hello from my experience, the best way to do this is to export different STL file for every single part and then merge them using a text editor.

You can find more details of how to merge the different STL files using a text editor in the step by step tutorial Step-by-Step Tutorial: Homework of Session 4
