Hello,

In my simulation the outlet-boundary is like this:

    <name>
    {
        type            totalPressure;
        uniform     0;
        p0         0;
    }

So it is athmospheric pressure at the outlet.

What if I rather want to have the same pressure outlet with 100 Pa instead of atmospheric pressure?

Is it true that the

uniform 0;

describes the initial pressure at t=0 and

p0  0;

describes the pressure at the outlet duiring the simulation?

If no, what are they standing for?


Thank you
Simon

Hi Simon,

I think this link may help you.

p0 uniform 0;

means that you are setting the value of 0 uniformly at your boundary patch (zero at the whole boundary patch). The solver will use this value and the velocity at this boundary to calculate the static pressure, as the equation in the link describes.

Regards.
