Pressure Inlet BC in starccm+
 
How to give pressure Inlet BC in CCM+ as it have only Pressure outlet BC and not allowing inflow from this BC, if applied at Inlet. Can we specify only pressure BC in CCM+. My case involes atm. BC at inlet & outlets and having rotating fan inside the volume. Thanks in advance..

use the stagnation bc

I've done similiar simulation using Pressure outlet at the inlet, it gave me reasonable data back, at least comparing with experiment, the only thing was ccm+ complaining about reversed flow in all inlet faces, but I do not know if it is correct to do it like this, it seems to work..

I also use for inlet BC pressure outlet, and there was reversed flow and i get results what i need...

it seems to work..

What about outlet BC. We have to prescribe at least one inlet and one outlet BC in fluid flow simulation. So if at domain inlet is forced pressure outlet BC what have to be forced at domain outlet?
