FEM rod element not collide with each other


Recommended Posts

I'm trying to simulate the effect of two fluffy spheres (made of fibres) colliding with each other.

But no matter what parameter I tried, these two spheres will never collide, but as if they are independent units each in their own environment.

The screenshot has collision visualization enabled.

Does anyone have an idea?

I've seen all these several times.

They are using either tet or solids with fibre-like structures connecting inside to do solid FEM simulation, not what I'm doing here.


Actually, there're little material about FEM rods in Houdini available on the Internet.
