flip fluid velocity field problems with viscosity on

Recommended Posts

Hi guys,

I have a problem: I'm making a cream/chocolate whirpool in a flip tank, with a donut coming from below the surface. then I woul like to throw in some nuts.
I put a custom velocity to generate the whirpoll but whe I turn on the viscosity in the solver a square appears (as you can see from the pics) and the fluid seems swirl around it. Any suggestions to get rid of that?

Thanks in advantage.

Hi,

Nobody can help me :D,

I notice tha the square in the middle is the colliding geometry (a torus), actually is the boundig box of the vdb.

Does anybody know why it only appears when a switch the viscosity on?

Thanks for your help

Nobody may know why off the top of their head, but if you posted a simple example of your setup, you would likely get an answer more quickly.
