Why does this happen?

PIMPLE: Operating solver in PISO mode

Thanks.

Hi,

take a look at $FOAM_SRC/finiteVolume/cfdTools/general/solutionControl/pimpleControl/pimpleControl.C. Here is an excerpt from the constructor:

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

where nCorrPIMPLE is

nCorrPIMPLE_ = pimpleDict.lookupOrDefault<label>("nOuterCorrectors", 1);

So if you have number of outer correctors below 2, algorithm will operate in PISO mode.

Thanks a lot! Makes more sense now!

i m having the same problem....can anyone tell its exact solution

Hi nirbhay,



you should simply go to your fvSolution file and add in your PIMPLE sub-dictionnary :

nOuterCorrectors         2;

(or even more Correctors)

Valuable inforamation ..keep doing

Hello nirbhay,
take a look at the book Mathematics, Numerics, Derivations and OpenFOAM® by Tobias Holzmann. It has a pretty good explanation how pimpleFOAM works.
