Hi,

The simpleFoam does not stop even there is no iterations any more. In fvSolution, the pUek is set as (tol=1e-5)

    p
    {
        solver          GAMG;
        tolerance       1e-05;
        relTol          0.05;
        smoother        GaussSeidel;
        nCellsInCoarsestLevel 20;
    }

    U
    {
        solver          smoothSolver;
        smoother        GaussSeidel;
        nSweeps         2;
        tolerance       1e-05;
        relTol          0.1;
    }

    k
    {
        solver          smoothSolver;
        smoother        GaussSeidel;
        nSweeps         2;
        tolerance       1e-05;
        relTol          0.1;
    }

    epsilon
    {
        solver          smoothSolver;
        smoother        GaussSeidel;
        nSweeps         2;
        tolerance       1e-05;
        relTol          0.1;
    }

And the solver does not stop even if tol<1e-5

Anyone knows why? Thanks.

my bad. there is certain info added in SIMPLE fvSolution dict
like,
residualControl
{
p 1e-5;
U 1e-5;
nuTilda 1e-5;
}
