Hi all,
does anyone have any insights into why any given case would not converge even though the plotted residuals are definitely below the max limits set?
Is this specific to solver/geometry/etc?



my fvSolutions:

SIMPLE
{
    nNonOrthogonalCorrectors 0;
    pMinFactor      0.2;
    pMaxFactor      1.5;

    residualControl
    {
        p               1e-3;
        U               1e-5;
        e               1e-3;

        // Possibly check turbulence fields
        "(k|epsilon|omega)" 1e-3;
    }
 }

If you compare this with the attached figure of residuals, we can clearly see that the max limits were reached much earlier than when it actually converged.
Why?
I do not notice any strange things in the log or any warnings etc.

Please look at the residuals of k and ε / ω first. May be there are larger residuals.
