Delete grains from existing hole ?


Recommended Posts

I want to kill any particles from going past this hole. I was thinking of finding the bounding box of the geometry but how do I find the area of the hole as to tell the particles to die when they hit the hole and or go outside of the hole with grains ?

In your case, couldnt you just kill them if they hit a P.y threshold?

Otherwise you could create an sdf for the hole and kill them inside a sopsolver if the volumesample() of the particles P is < 0
