Hi, I'm trying to run simpleFoam on OpenFoam 4.1 using:

foamJob simpleFoam

and I receive:

Application : simpleFoam
Executing: /opt/openfoam4/platforms/linux64GccDPInt32Opt/bin/simpleFoam > log 2>&1 &

and when I check top command nothing is running.

I have no idea where to begin to solve this error, if anyone has any insight I would very much appreciate it.

I have modified the motorBike tutorial

Forgive me as I am new to CFD and OpenFOAM.

Thank you

It looks to me that foamJob is running simpleFoam in the background and put the process log in a log file. Try to look for the log file.

You can run the case using only simpleFoam. Your command window should show you all the process

Thanks for the reply.

The command window shows me nothing it just stays on

Application : simpleFoam
Executing: /opt/openfoam4/platforms/linux64GccDPInt32Opt/bin/simpleFoam > log 2>&1 &

and if i click enter again i get

Sorry if I am not explaining this properly I am quite new to CFD and OpenFoam.

Sorry I didn't explain clearly. What I mean is instead of typing " foamJob simpleFoam", you should use only "simpleFoam" to run your case. Try it

Ah thanks, oh a whole bunch of warnings appeared. I guess I should start going through these and fixing them.

Thank you for your help

I've managed to fix some of the errors, but I'm left with this. Does anyone know how to approach this?

Hello

you are missing "cumulative" within subDict binData in your foceCoeffs functionObject. It should look something like this:

forceCoeffs1
{
    type        forceCoeffs;

    functionObjectLibs ( "libforces.so" );

    outputControl   timeStep;
    timeInterval    1;

    log         yes;

    patches     ( motorBikeGroup );
    rhoName     rhoInf;      // Indicates incompressible
    rhoInf      1;           // Redundant for incompressible
    liftDir     (0 0 1);
    dragDir     (1 0 0);
    CofR        (0.72 0 0);  // Axle midpoint on ground
    pitchAxis   (0 1 0);
    magUInf     20;
    lRef        1.42;        // Wheelbase length
    Aref        0.75;        // Estimated

    binData
    {
        nBin        20;          // output data into 20 bins
        direction   (1 0 0);     // bin direction
        cumulative  yes;
    }

}
