Hi,

I am new to OpenFOAM and running a laminar flow in a tube using simplefoam, with a pressure inlet and a flowrate outlet. My simulation always diverges with large continuity errors(continuity errors). Any suggestion for this situation? Thanks!

Here is my boundary condition setup:
U:
dimensions [0 1 -1 0 0 0 0];

internalField uniform (0 0 0);

boundaryField
{

inlet
{
type outletInlet;
outletValue uniform (0 0 0);
value uniform (0 0 0);
}

outlet
{
type flowRateOutletVelocity;
volumetricFlowRate 5.676455641980107e-07;
value uniform (0 0 0);
}

walls
{
type noSlip;
}

}

P:
dimensions [0 2 -2 0 0 0 0];

internalField uniform 0;

boundaryField
{
inlet
{
type fixedValue;
value uniform 12.3260377358;
}

outlet
{
type zeroGradient;
}

walls
{
type zeroGradient;
}
}

Thanks in advance
