Hi, I start a simulation which has a rotating zone, but I don't know what can do this in FOAM, could anyone help me?

Best Regards.

I'd suggest you check out these threads (the search function of the MessageBoard might give you further hints):

Hi Andy,

If you are looking for a tutorial on rotor-stator interaction, have a look at icoTopoFoam, mixer2D.

If you only want to compute the flow in a rotating reference frame, add something similar to the following to a suitable solver:

dimensionedVector Omega
(
"Omega",
dimensionSet(0, 0, -1, 0, 0),
vector(0, 2*M_PI/60*(-595), 0) //The last number is RPM
);
// Calculate the centrifugal force
volVectorField Fcent = (Omega ^ (Omega ^ mesh.C()));

tmp<fvvectormatrix> UEqn
(
fvm::div(phi, U)
+ turbulence->divR(U)
+ (2*Omega ^ U) // Coriolis force
+ Fcent // Centrifugal force, computed ONCE above
);

Håkan.

Thank you for your reply.
And I think I am looking for the rotor-stator interaction.
