paniruro Posted August 2, 2020 Share Posted August 2, 2020 (edited) 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. Edited August 5, 2020 by paniruro Quote Link to comment Share on other sites More sharing options...
paniruro Posted August 5, 2020 Author Share Posted August 5, 2020 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 Quote Link to comment Share on other sites More sharing options...
ryew Posted August 5, 2020 Share Posted August 5, 2020 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. Quote Link to comment Share on other sites More sharing options...
