Hi guys, I was trying to do what seems like a very basic thing, but failed miserably at it. I have a scene with flip fluid in a hole, and I am translating a cube collider up from the bottom, to push the water out of the hole. What happens though, is that the water just compresses and the water is not pushed out. I would be super happy to know what I am doing wrong, is there a setting that I am missing? I attatched the hipnc file and a screenshot. Bjørn

Hello, this should work:

Tanto Hello, this should work:Amazing, it works!
So you just added a trail before the collider and set it to compute velocity to get it to work?
Was it missing the directional velocity from the collider?

No, what made it work was just using the model rather than the vdb as a collider. But if you used a vdb you would need a velocity field, as there is no way for the solver to understand its animation otherwise.
