Hello!

I tried to simulate a simple airflow with the kEpsilon model, solver simpleFoam. a totalPressureInlet with 0.44 pa is given. Velocity has to be calculated. The residuals and the continuity looks good but the velocity much to small about 1e-06. the Solution should be about 0.35 m/s.

BC:

U:
internalField uniform (0 0 0);

outlet: type zeroGradient;

inlet: type pressureInletVelocity;
value uniform (0 0 0);

wall: type fixedValue;
value uniform (0 0 0);
------------------------------------------------------------
p:
internalField uniform (0 0 0);

outlet: type zeroGradient;

inlet: type totalPressure;
p0 uniform 0.44;
value uniform 0.44;
gamma 1;

wall: type zeroGradient
------------------------------------------------------------
epsilon:

internalField 0.02247;
outlet: type zeroGradient;

inlet: type turbulentIntensityKineticEnergyInlet;
intensity 0.001;
value uniform 0.02247;

wall: type epsilonWallFunction;
value uniform 0.02247;
---------------------------------------------------------------------------------------
k
internalField uniform (0 0 0);

outlet: type zeroGradient;

inlet: type turbulentMixingLengthDissipationRateInlet;
mixingLength 0.01;
value uniform 1.356e-03;

wall: type kqRWallFunction;
value uniform 1.356e-03;

Has anyone a hint for me ?
