If Ux and Uy are constant only then the derivative in there respective direction that is dUx/dx = 0 and dUy/dy = 0 only hence you can specify velocity with zeroGradient at Inlet face. |

hello sharma,
exactly, but I want to implement Ux and Uy equal exactly to zero other than constant value but Uz to be a constant value. Currently im running with zeroGradient conditions but it doesn't guarantee Ux=Uy=0 Am I correct Thanks |
