Hi,

I am trying to solve a fan tutorial from "Chalmers University of Technology, CFD with OpenSource software 2010, Implementation of an actuator disk in OpenFOAM". First, the tutorial OpenFoam version does not fit with my version, OpenFOAM-
1.5-dev and OpenFOAM-v1612+, respectivily. So, I modified the scripts in order to compile correctly the example, and add nu and nuTilda files. But, for some reason, the results for the pressure and velocity do not look like for the one in the tutorial.

Can you help me? because I am new in OpenFoam and I do not know what I did wrong.

I will paste the p and U files, for your comments

p:
boundaryField
{ inlet {
type totalPressure;
p0 uniform 0;
phi phi;
U U;
rho none;
psi none;
gamma 1.0; }
outlet
{
type fixedValue;
value uniform 0; }

walls
{
type zeroGradient; }
left
{
type fan;
patchType cyclic;
f List<scalar> 2 (10.0 -1.0);
value uniform 0; }
right
{
type fan;
patchType cyclic;
f List<scalar> 2 (10.0 -1.0);
value uniform 0; }
}

U:
internalField uniform (1 0 0);
boundaryField
{
inlet {
type pressureInletVelocity;
phi phi;
rho rho;
value uniform (0.0 0.0 0.0); }
outlet
{
type inletOutlet;
inletValue uniform (0.0 0.0 0.0);
value uniform (0.0 0.0 0.0); }
walls
{
type fixedValue;
value uniform (0.0 0.0 0.0); }
left
{
type cyclic; }
right
{
type cyclic; }
}

Best regards.
Carlos
