Problem with mesh of part

General Questions
1

Good morning,
I’ve problem with meshing parts included to this topic. I get information after trying meshing “Mesh generation failed for part. Check geometry and/or adjust meshing parameters”.
I know that program has problem with arcs - when I delete it, everything was okay but after analise it, the maximum force was very big and I know that it’s not true - I need analyse it with this arcs.
I tried to set different parameters of meshing but without results. Could you help it is possible to get properly meshing to this part?

It would be better to model those thin-walled pipes using shell elements (so you would need to import surface geometry).

But to generate tetrahedral mesh here, you should reduce the maximum element size since the default one is too large.

If you want to stick with solid elements, you could try fixing the small edges in CAD first. I would also suggest combining in CAD (Boolean Add) instead of a Compound part in PPM.

Okay, I did it. I didn’t see before that thickness of arcs is 2,4 mm but thickness of pipes is 2,6mm… Now everything is okay. Thank you!
