I am trying to run the simpleFoam solver but get the following 'error' in the terminal:

Code:
/*---------------------------------------------------------------------------*\

What must I do to be able to run a solver from a case directory stored anywhere on my computer?

Thank you in advance.

Hi,

The "keyword BLABLA is missing" always means, that the solver is missing something in a certain file.
So you in this case "SIMPLE" is missing in the file fvSolution.

This is how it is supposed to look:

Code:
SIMPLE
{
        nNonOrthogonalCorrectors 1;
    residualControl
    {
            p               1e-5;
            U               1e-5;
        k        1e-5;
        omega        1e-5;
    }
}
It just tells the simpleFoam solver how to handle some things such as the number of nNonOrthogonalCorrectors and residual control. Normally you need to copy and paste these things from older cases. I guess you will find such a piece of code in your fvSolution file but for a different solver (PIMPLE, PISO, ??)

Philipp.

I know. I asked the same questions a few months ago and was happy about the help here...
