Hi;

How could I apply velocity force to an ocean fluid, using an animated geometry?

(I think I should use volume, but I don't know how).



Thanks.

Hi,

In your scene, your box isn't animated.

If you just want a force pushing on z axis,
- plug a popforce in the second input of the flipsolver and set the force to 0,0,1. You can also animate this values.

If you want your box to move and interact with the flip,
- animate your box by keyframing a transform node
- plug a staticobject in the merge1 of your dop
- refer your animated geo in the sop path of the staticobject, check “Use deforming geometry” and “Use object transform”. You can use surface collisions or volume collisions, they both work. Thought, I don't know which one is the most efficient method.

You can also create a vel field from your box normals or with noises and advect your flip with it.

I hope that helped. Have a good day !
