I’m trying to decompose the domain in a way so that way I can sweep but not sure if that’s the right strategy. I decompose at every angle but I get to my last piece and it’s not sweepable. Is there a better way to do this?
Thank you
Yeah, here is the general geometry that I’m trying to do. I also tried to decompose in a circular direction.
Thank you

Well, I had some time to burn while waiting for a debugging session to hit a breakpoint… so I gave it a shot… how does this look?

The key to getting this mesh was to not extend the cut that separates the 90-degree bend into the back-half of the model, and then to composite the remaining small surface with it’s larger neighbor (see the dashed green line):
Wow, this is great. Thank you. This helps me a lot moving forward.
Do you know of a different way to decompose this domain? I’m experiencing clustering in this location:
