my cad is a solid model still while creating an enclosure, it shows that no solid part is present. can someone help me with this??
Can you share the link to your project with the issue?
i have invited you to the project. Please refer to the part which has colourful bodyworks. Thanks in advance
I looked at the geometry “body_and_sidepods_v1” and this part does not contain a valid solid so the only geometry imported is surface geometry which Simscale cannot use.
I imported the STEP file into Onshape and and it came across with many errors and it would not import as a solid either. Below is an example of one or the problem areas I found. I also see quite a few edges less than .5mm. If this is a valid solid in Fusion 360 you can try to see if you can export a Parasolid file format. It might work better but I don’t think it can fix all the issues.
The geometry "body_and_sidepods_v13"has all the same issues above as well as issues with the tube. I see many of the tubes interfere with each other which will cause issues. One thing that typically helps is if you merge all the parts into a single body.
I hope this helps. Please let us know if you have any other questions. I will also tag the @CFD-SQUAD, they may have some better suggestions on how to prepare the geometry cfd analysis.
