After i run the potentialFoam

a error occured

keyword SIMPLE is undefined in dictionary ".../system/fvsolution"

i have checked the fvsolution file, there doesn't not have any 'SIMPLE' inside.

Does anyone know how to fix the problem?

Thanks you very much~

When I add temperature equation to simpleFoam, I have same problem.

You must be running it on simpleFoam. If the fvsolution contains PISO, this error might occur. I hope that solves your issue.

hi everybody,

If you are solving the velocity and pressure by SIMPLE algorithm you must add the following to fvSolution:

Code:
SIMPLE
{
    nNonOrthogonalCorrectors 0;
    pRefCell        0;
    pRefValue       0;

    residualControl
    {
        p_rgh           1e-2; // when you need dynamic pressure
        U               1e-4;
        T               1e-2;

        // possibly check turbulence fields
        "(k|epsilon|omega)" 1e-3;
    }
}
for more information about SIMPLE algorithm and how to use it see the below link:
