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:

Don't use outflow bc in this case, it's not got any setting to hold the water in the domain so chances are the failure is down to the zone trying to empty very quickly.
