Hi everyone,

I am trying to find a boundary condition for an outlet patch. It should be a non uniform field, with fixed volumetric flow rate with the possibility of reverse flow rate.

The specified outlet flow should come from the integration of the flow over the patch, so, there could be reverse flow but at the end the sum of the flow on each cell will be the specified volumetric flow.

Could there be a boundary condition with this characteristics?
