Inside closed mesh goal

I think the code I posted in this thread might be what you need:

Kangaroo 2 Solid Point Collide Bug/Significant increase in calculation time

Solid_pt_newCollide_4.gh (55.6 KB) Tracked down the issue - it wasn’t what I first thought. The problem was that when a particle had crossed the mesh once since the previous iteration, and ended up inside, I was pulling it back to that crossing. However, that was introducing a spurious tangential component. Switching to always pulling to the closest point fixes this.
