Hello
I am trying to model the flow of a liquid partilce with high density and viscosity suspended in water in a 3D-bend using VOF method. When I run the simulation without the particle my velocity field seems to converge, but when I adapt a spherical region with a specied radius and run the VOF solver I get an error " too many VOF sub-time steps. the velocity is probably diverging. Please reduce the time steps if necessary" . I even tried reducing the time step size. I'm pretty sure that my grid is fine. I would greatly appreciate if you can help me out. Thank you very much |
