Hi All ,
I know you can use the Source volume DOP to create a source for a flip fluid , but like wise I expect you can set a Fluid source SOP to act as a collision volume for the flip sim. In Dops though which input on the flip solver is the source volume dop added to .

I can successfully create RBD objects as a collision object, but was interested is I could use the source volume dop. If anyone has an example file I would be greatful !

This example uses sdf for collision.

Note: If you have moving collision geo then you have to create collisionvel vdb as well.

I personally prefer vdb most of the time. I found it very fast than rbd.

All these examples are excellent ! collisionvel gets created by default with the fluid source sop when set to collision , No doubt missed something minor somewhere ..
