Particles fall through object

[johnnelsonvfx]

In this simulation i am having the hands hit the ledge and create a dust of particles. it seems that the particles are falling through the ledge and some others are not. does this have to do with cell size? It is currently out a low value in cm.

i suppose they are simple drag particles?
what actually you are trying to do?

[johnnelsonvfx]

The hands are jumping from one building to the next, the jumper lands hand first on the ledge. Kicking up dust ( attempt to mix the elements better) want to kick ups some dust.

i see, now
the particles should not enter the geometry, here is my suggestion:
- be sure that circumscribed voxelization is used (interaction panel)
- close the geometry, in general it's better to simulate with closed geometry objects
