[BUG] Particle contact forces in VDB
Bug Description
Maybe I'm missing something, but it looks like the particle self-contact forces and hessians are not being zeroed for every iteration in the non-self contact version of the vdb integrator.
System Information
No response
In fact, they're not applied at all. This means the non-self-colliding version of the integrator also ignores particle-body collisions.
Many thanks!
