Hello everyone, I'm new at working with OpenFoam and an error appear while running
mpirun -np 8 pimpleDyMFoam -parallel
I can't figure a way to solve it.
The error is:

--> FOAM FATAL IO ERROR:
[4] keyword cellMotionU is undefined in dictionary "IOstream.solvers"
[4]
[4] file: IOstream.solvers from line 0 to line 0.
[4]
[4] From function dictionary::subDict(const word& keyword) const
[4] in file db/dictionary/dictionary.C at line 608.

I'm grateful for any help you can provide me. Thanks. Daniela

Hi,

Do you have something like

Code:
...
    cellMotionU
    {
        solver          PCG;
        preconditioner  DIC;
        tolerance       1e-08;
        relTol          0;
    }
...
in your fvSolution? If yes, could you post case files, this way it is simpler to find the problem?

First of all thank you so much for answering me!

So I add to my fvSolution the part that was missing. But I go another error that I can't solve.
--> FOAM FATAL IO ERROR:
[6] keyword div((nuEff*dev(T(grad(U))))) is undefined in dictionary "IOstream.divSchemes"

My fvSchemes is the following:

/*--------------------------------*- C++ -*----------------------------------*\

| \\ / O peration | Version: 1.6 |

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

ddtSchemes
{
default Euler;
}

gradSchemes
{
default Gauss linear;
grad(p) Gauss linear;
grad(alpha) Gauss linear;
}

divSchemes
{
default none
div(rho*phi,U) Gauss vanLeerV;
div(phi,alpha) Gauss vanLeer;
div(phirb,alpha) Gauss vanLeer;
div(phi,U) Gauss linear;
div(phi,epsilon) Gauss linear
div((nuEff*dev(T(grad(U))))) Gauss linear;
}

laplacianSchemes
{

}

interpolationSchemes
{
default linear;
}

snGradSchemes
{
default corrected;
}

fluxRequired
{
default no;
p;
pcorr;
alpha;
}

Can you help me?

Hi,

Semicolon after "div(phi,epsilon) Gauss linear" is missing (so the next line with "div((nuEff*dev(T(grad(U))))) Gauss linear;" is eaten by it, and as a result you have got error message about undefined keyword).
