To ensure rapid convergence, the under-relaxation factor for the pressure equation will be reduced. To do this:

Select the Solvers > Segregated Flow > Pressure node.

In the Properties window, change the Under-Relaxation Factor to 0.15.

The default stopping criterion is for the run to stop after 1000 iterations. This may be reduced for the current case.

Select the Stopping Criterion > Maximum Steps node.

Change the Maximum Steps property to 600.
