Hi,
I am quite new to OpenFOAM so if any important Information is missing, just ask for it.

Solver: chtMultiRegionFoam
OF-Version: v1812

I have a Problem with the outerCorrectorResidualControl in PIMPLE Mode (Solver: chtMultiRegionFoam) when using OpenFOAM v1812 while on OpenFOAM 6 it works fine. (I use OpenFOAM 6 on my Computer but on our Cluster OpenFOAM v1812 is installed, so I can not change anything on this.)

I'm defining the general PIMPLE-loop in the fvSolution-file placed in the system folder. The outerCorrectorResidualConrol is given in the system/<material>/fvSolution files.

system/fvSolution:
Code:
PIMPLE
{
    nOuterCorrectors 50;
    nCorrectors     1;
    consistent      true;
    nNonOrthogonalCorrectors 0;
    turbOnFinalIterOnly false;
}
system/fluid1/fvSolution:
Code:
solvers
{
    rho
    {
        solver          PCG;
        preconditioner  DIC;
        tolerance       1e-7;
        relTol          0.1;
    }

    rhoFinal
    {
        $rho;
        tolerance       1e-7;
        relTol          0;
    }

    p_rgh
    {
        solver           GAMG;
        tolerance        1e-7;
        //relTol           0.01;
        smoother         DIC;
	maxIter		 20;
    }

    p_rghFinal
    {
        $p_rgh;
        tolerance        1e-7;
        relTol           0;
    }

    "(U|h|k|epsilon|R)"
    {
        solver           PBiCGStab;
        preconditioner   DILU;
        tolerance        1e-7;
        relTol           0.1;
    }

    "(U|h|k|epsilon|R)Final"
    {
        $U;
        tolerance        1e-7;
        relTol           0;
    }
}

PIMPLE
{
    
    momentumPredictor   true;
    nOuterCorrectors 50;
    nCorrectors     1;
    consistent      true;
    nNonOrthogonalCorrectors 0;
    turbOnFinalIterOnly false;
    outerCorrectorResidualControl
    {
        p_rgh
        {
            tolerance 1e-3;
            relTol 0;
        }
    }
}

relaxationFactors
{
    equations
    {
	"U.*"		0.5;
	"(h|e).*"	0.3;
	"(k|epsilon).*"	0.2;
    }
    fields
    {
    	"p_rgh.*"       0.7;
    }
}
system/solid1/fvSolution:
Code:
solvers
{
    h
    {
        solver           PCG;
        preconditioner   DIC;
        tolerance        1e-06;
        relTol           0.1;
    }

    hFinal
    {
        $h;
        tolerance        1e-06;
        relTol           0;
    }
}

PIMPLE
{
    
    momentumPredictor   true;
    nOuterCorrectors 50;
    nCorrectors     1;
    consistent      true;
    nNonOrthogonalCorrectors 0;
    turbOnFinalIterOnly false;
    outerCorrectorResidualControl
    {
        h
        {
            tolerance 1e-2;
            relTol 0;
        }
    }
}
When using OF 6 the outerCorrectors loop is left if all ResidualControl criteria are fulfilled (solid1 & fluid1). But when using OF v1812 the solver allways run the 50 OuterCorrector loops (probably without reading the ResidualControls).

What am I doing wrong, or how can I use ResiualControls in chtMultiRegionFoam with OF v1812? Any idea would be helpfull.

Thanks for your help
Kobi
