Hi @ajeet20, thanks for sharing
A few comments:
- You have sheet bodies in your assembly. These are not supported by SimScale
- Some bodies are way too detailed, this will be problematic in the meshing step. Keep only the primitive shapes and the necessary details
- I’m not sure what you’re going for here, but you don’t seem to have a flow region, which is necessary for the fluid portion of the analysis, if it exists
Cheers
Igor
