Volume as a collision doesn't works, why?

[Masoud]

Hi;

In my FlipFluid simulation, I tried to use a volume as a collision, but it doesn't work.

How can I fix this?

 

 

Thanks for helping.

First, for volume collisions, you have to use distance VDB (SDF), not fog VDB.

 

I think the collision function inside the "volume source" node is only for smoke, for example when a fast-moving object adds turbulence to your simulation. 

You can easily use the "static object" node for FLIP collisions.
