CFD Online Discussion Forums - Error while running simpleFoam

Dear all,

I have a problem while trying to run simpleFoam.

I think I set all right, but I get this:

Code:

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

Create time



Create mesh for time = 0



Reading field p



Reading field U



Reading/calculating face flux field phi







--> FOAM FATAL IO ERROR: 

Unable to set reference cell for field p

    Please supply either pRefCell or pRefPoint





file: /root/Documents/OF_case1_test/system/fvSolution::SIMPLE from line 81 to line 89.



    From function void Foam::setRefCell

(

    const volScalarField&,

    const volScalarField&,

    const dictionary&,

    label& scalar&,

    bool

)

    in file cfdTools/general/findRefCell/findRefCell.C at line 115.



FOAM exiting

Does anyone know how to solve this?

Thanks,
