Hi...

I'm doing the open channel flow simulation with interFoam solver and I got a exaggerated elevation upstream the cylinder (http://d.pr/i/Ya1d).



I dont't know why... I use these BC to the atmosphere:

alpha 1
{
type inletOutlet;
inletValue uniform 0;
value uniform 0;
}

U:
{
type pressureInletOutletVelocity;
value uniform (0 0 0);
}

p_rgh:
{
type totalPressure;
p0 uniform 0;
U U;
phi phi;
rho rho;
psi none;
gamma 1;
value uniform 0;
}
k
{
type inletOutlet;
inletValue uniform 0.001;
value uniform 1e-11;
}
nuSgs:
{
type zeroGradient;
}
nuTilda:
{
type inletOutlet;
inletValue uniform 0;
value uniform 0;
}

Help me please!

Best regards!
