Hi everyone,
I am just simulating a planar poiseuille problem but with non-Newtonian Herschel Bulkley fluid. The problem I'm solving is showing reasonable velocity profile and pressure drop, but when monitoring initial residuals, shows me some weird behaviour. I wanna know what the issue with my case in terms of residuals. I should mention that I'm using fvOption to have a periodic domain.

{
    p
    {
        solver          GAMG;
        tolerance       0;
        relTol          0.1;
        smoother        GaussSeidel;
    }

    pFinal
    {
        $p;
        smoother        DICGaussSeidel;
        tolerance       1e-06;
        relTol          0;
    }

    "(U|k|nuTilda)"
    {
        solver          smoothSolver;
        smoother        symGaussSeidel;
        tolerance       1e-05;
        relTol          0.1;
    }

    "(U|k|nuTilda)Final"
    {
        $U;
        tolerance       1e-05;
        relTol          0;
    }
}

Is there anyone to help me with these pimpleFoam strange residual values?
