Hello,


I'm running an open channel flow simulation in Ansys Fluent and my idea is to try different combinations of inlet and outlet boundaries conditions. However, when I try the combinations


inlet: mass-flow-inlet --- outlet: outflow
inlet: pressure-inlet --- outlet: outflow


The program shows an error message at the second interaction:

Also, as you can see in the image (behind the error message), the flow's behavior is really weird

I can't find what is happening...



When I use other combinations, the simulation works just fine.





The simulation is an open channel flow with water and the viscous model is the standard k-epsilon (I also tried k-omega) model.


Thank You
