In my model, the flow has constant flow rate 31.2 square milimeter/sec
of course 2D domain.. Using velocity inlet boundary condition, I must set the upper condition. Please help me.. I really wonder about that. |

adapt the right Velocity U.
Q = U . A --> U = Q/A In your case you have to divide your massflow rate with the inlet length (in your 2d-case)
