I'd like to create a static/rest position fluid box that has no motion. Then drop a rbd obj straight through the fluid box from the top. In theory this creates a velocity field??? Then I can use that data to advect points in pops.

The only way I've been able to get anything to work is by starting with a default Smoke Container and Smoke from object. The object and container being the same size, so the smoke can't leave the container. Then dropping the rbd through it.

The problem is. I don't want to use the smoke. I just want the rbd object to create the velocity field with the standard container.

Just trying to understand the workflow with dops fluids

Any ideas would be much appreciated.

Later
