Hello.

I want to do pseudo-transient simulation using PIMPLE in pitzDaily.

When I change the default settings in fvSolution in pitzDaily, for PIMPLE to:

Code:
PIMPLE
{
    nNonOrthogonalCorrectors 0;
    nCorrectors          2;
    nOuterCorrectors    50;
    turbOnFinalIterOnly on;
    residualControl
    {
        "(U|k|epsilon)"
        {
                tolerance  1e-5;
                relTol      0;
        }
        p
        {
                tolerance  1e-4;
                relTol      0;
        }
     }    
}
 
relaxationFactors
{
    fields
    {
        p      0.7;
        pFinal   1;
    }
    equations
    {
        "U|k|epsilon"          0.8;
        "(U|k|epsilon)Final"   1;
    }
}
then I have residuals like in attachment. How can I know when simulation has converged to a steady state, at least according to residuals? Where can I find more information about this?

Regards,
Darko
