Default Inlet, No Outlet Pressure Simulation

Enternald is on a distinguished road
Hi everyone,

I want to simulate a box (initially at P = 0atm), increasing in pressure over time as it gets filled by room temperature air. The pressure is introduced through the hole inlet (P = 1atm) at the top of the box. I am looking for suggestions on the best solver to perform this simulation. I tried using rhoPimpleFoam, however after a short period of time I receive an unspecified error using the following boundary conditions.

U:
wall
{
type zeroGradient;
}

inlet
{
type pressureDirectedInletVelocity;
inletDirection ( 0 0 -1 );
value $internalField;
}

P:
wall
{
type zeroGradient;
}

inlet
{
type totalPressure;
gamma 0.0;
p0 uniform 101325;
}

Any suggestions would be greatly appreciated!
