[flow_CH]

''Hello
I am modeling an open channel flow with two inlet for air and water (velocity inlet). Without using "Open channel flow"
In middle of channel i have two pressure inlet for entraining air into the flow.
In steady state, i do not have problem but in unsteady state, i ran the solver and everytime the flow arrive to middle of channel, fluent write: "solution is converged" but it is keeping the solve and does not stop.
what is that problem?
I should say the residuals are arriving to residual criteria and they are 0.001 for all
please see attached image
Thanks
