[immortality]

I have set these parameters at Pimplefoam:

PIMPLE
{
    momentumPredictor yes;
    nOuterCorrectors 2;
    nCorrectors     3;
    nNonOrthogonalCorrectors 0;
    rhoMin          rhoMin [ 1 -3 0 0 0 ] 0.1;
    rhoMax          rhoMax [ 1 -3 0 0 0 ] 5.0;
}

and this error appears.why?whats the difference between two above correctors(nOuterCorrectors and nCorrectors) exactly?can abyone explain it to me?

Create time

Create mesh for time = 0


PIMPLE: no residual control data found. Calculations will employ 2 corrector loops

Figured it out?

Regarding the difference between inner and outer correctors, have a look at this guide.
