All tolerances are set to 1e-13, and it's converging fine, but I would like for it to run until the stop time, not stop at convergence. I have searched around quite a bit and was unable to find anything that helped.

controlDict:

FoamFile
{
    version     2.0;
    format      ascii;
    class       dictionary;
    location    "system";
    object      controlDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

application     simpleFoam;

startFrom       startTime;

startTime       0;

stopAt          endTime;

endTime         10;

deltaT          0.0005;

writeControl    timeStep;

writeInterval   5;

purgeWrite      0;

writeFormat     ascii;

writePrecision  6;

writeCompression off;

timeFormat      general;

timePrecision   6;

runTimeModifiable true;

functions {

    #include "forceCoeffs"
}

In fvSolution file, within the SIMPLE solver parameters, set the residualControl values to very small numbers (eg. 1e-9). This should keep the solver running until the specified end time.

They're already at 1e-12, I'm guessing I should just lower them even more? Just so I know what's going on: It runs until it hits the stop time or achieves the residual condition, correct?

SIMPLE
{
    nNonOrthogonalCorrectors 0;

    residualControl
    {
        p               1e-12;
        U               1e-12;
        "(k|epsilon|omega)" 1e-12;
    }
}

Correct.

But may I ask why it is necessary to run until a particular end time? The time really has not meaning in a simpleFoam calculation. It simply functions as a means to iterate on the solution. So running until some particular physical time really does not make sense. If this is desired, you should use pimpleFoam.
