Hello.
I'm beginner of fluent. these days, I have been making 2 material Couette flow. Upper wall moving velocity : 0.01 m/s Bottom wall fixed above the bottom wall, there is water layer(1mm) above the water layer, there is oil layer(1mm) Upper moving wall draw the oil. In this situation, I don't know how to set-up the middle point(between water and oil) on the Gambit or fluent. it's not wall then what? I try it by wall, interior, interface. but I fail to make flow. please help me. |

the middle is a free surface, you should not set any boundary condition at that plane. it is a multiphase flow problem with free surface. tried to use VOF method to identify the free surface betweet two fluids
