Fixing mesh swirls

Hey there! I’m constantly on the lookout for new fields to explore, and I recently stumbled across Grasshopper—so I’m still very inexperienced when it comes to programming in it. I set myself the challenge of modeling a parametric Frei Otto–style cable roof, but once I apply Kangaroo physics, some weird swirls appear near the center messing up my mesh (which I intend to use as a base for the cables)

Is this happening because of the way I designed the surfaces and meshes, or did I mess something up in the Kangaroo setup itself? I’d really appreciate any help. Thanks in advance!

Your initial mesh had internal naked edges. Align Vertices helps.

The solution is the same as @martinsiegrist

Thank you guys so much! You’re truly the best :slight_smile:
