Hi,

When I want to run my simulation with pimpleDyMFoam command I get the following error Message:

--> FOAM FATAL IO ERROR:
Unable to set reference cell for field p
Please supply either pRefCell or pRefPoint

Does anybody now where I can supply either pRefCell or pRefPoint?


Thanks in advance,
alex

Hi

check this out:

less $FOAM_TUTORIALS/incompressible/pimpleDyMFoam/mixerVesselAMI2D/system/fvSolution

Thanks Phicau,

found it.

Thanks Phicau. I also ran across the same error.

I also came across similar problem, potentialFoam complained about pRefCell, phiRefCell, and Phi. Luckily after adding those keywords to fvSolution, it solved.
Here are several keywords you may need.

PIMPLE 
{ 
    pRefCell 0; 
    pRefValue 0; 
} 

solvers 
{ 
    Phi 
    { 
        solver          GAMG; 
        smoother        DIC; 
        cacheAgglomeration on; 
        agglomerator    faceAreaPair; 
        nCellsInCoarsestLevel 10; 
        mergeLevels     1; 

        tolerance       1e-06; 
        relTol          0.01; 
    } 
} 

potentialFlow 
{ 
    nNonOrthogonalCorrectors 10; 
    PhiRefCell 0; 
    PhiRefValue 0; 
}

Dear users,

I do have exacly the same pRefCell error than Alexander but I already have the code of fvSolutions as you mentioned, with pRefCell 0; and pRefValue 0; set.

Does anyone know what is going on?

Most likely your simulation doesn't like cell 0. You can try pRefPoint and set a point somewhere in your domain.

I have already tried this option without good results

Well, I had the same problem with fsiFoam case running in parallel using consistentIcoFlow solver, but the thing is you need to add pRefCell and pRefPoint in fluid/constant/flowProperties for all processors as the fallowing:


flowModel consistentIcoFlow;

icoFlowCoeffs
{
nCorrectors 3;
nNonOrthogonalCorrectors 1;
pRefCell 0;
pRefValue 0;
}

//consistentIcoFlowCoeffs
consistentIcoFlowCoeffs;
{
nCorrectors 3;
nNonOrthogonalCorrectors 1;
pRefCell 0;
pRefValue 0;
}
