Source term using PisoFoam

sylv20 · April 13, 2015, 04:36

Hi,

I want to use pisoFoam with periodic boundary conditions. I usually use simpleFoam or pimpleFoam using the momentumSource into the fvOptions file, but it doesn't seem to be available with pisoFoam. Can anyone confirm that? Do i need to implement the momentum source directly into the solver ?

Thanks

Sylvain

Hi,

No, there is no fvOptions functionality available in pisoFoam. Though, if you set nOuterCorrectors to 1, you can turn pimpleFoam into pisoFoam. Below is an excerpt from pimpleControl.C:

Code:

    if (nCorrPIMPLE_ > 1)
    {
        ...
    }
    else
    {
        Info<< nl << algorithmName_ << ": Operating solver in PISO mode" << nl
            << endl;
    }
