Hello everyone,
I need to model a system that operates with a fan at the inlet and a exhaust at the outlet. I would like to know appropriate boundary conditions in order to use the fan curve and the exhaust curve simultaneously at the simulation. Is it even possible? What other options do i have?

I am used to execute simulations with fan curve only on the inlet, for these cases, i use the following BCS:

p

inlet
{
type fanPressure;
}
outlet
{
type fixedValue;
value uniform 0;
}
walls
{
type zeroGradient;
}

and U:

inlet
{
type pressureInletOutletVelocity;
value uniform (0 0 0);
}
outlet
{
type inletOutlet;
inletValue uniform (0 0 0);
value uniform (0 0 0);
}
walls
{
type noSlip;
}

Any suggestions are welcome.

Best regards
