Hi
I'm using StarCCM+ for a rotating flow simulation. I would like to specify a mass flow inlet boundary. On this boundary, the flow is rotating, and I would thus like to specify a tangential velocity distribution. Is it possible to specify this velocity in addition to the mass flow rate? Best regards Bernard |

Hi,
I think that in any CFD software, you can't specify both mass flow & velocity in single inlet boundary surface. It is not applicable. Depends upon your mass flow rate or velocity input, another value is calculated by solver itself. If you want to specify tangential velocity at inlet, then use velocity inlet boundary condition and specify tangential velocity. Hope this will help U
