Hi all,
I'm running a case using dynamic mesh to simulate flow in a valve. But the pressure solution is going diverged (fluctuation, value keeps going up and down), so the dynamic mesh is always generating negative volume. Yesterday, I try to enable the smoothing function in dynamic mesh model. It worked, the pressure field became reasonalbe. But today I tried again, it doesn't work anymore. OMG, who can help me. I just don't know what's the reason. Thanks. |
