Hi all,

I' m currently studying a 2D section of a motorbike for my final thesis project.
While trying to run the solver pimpleFoam the simulation do not start and openFoam report this error:

--> FOAM FATAL IO ERROR:
wrong token type - expected Scalar, found on line 20 the word 'uniform'

file: /home/tommy/Università/OpenFoamCases/SezioneMoto2D/0/p/boundaryField/outlet/value at line 20.

From function Foam::Istream& Foam::operator>>(Foam::Istream&, Foam::doubleScalar&)
in file lnInclude/Scalar.C at line 101.

FOAM exiting

.

Now, i triple checked that the boundary conditions on my /0/p file where correct but i post it here since it seems that the cause of the problem is located there.
Line 20 is the line where internalField value is set.

p file (i removed the header for the sake of clarity)

FoamFile
{
version 2.0;
format ascii;
class volScalarField;
location "17877";
object p;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions [0 2 -2 0 0 0 0];

internalField uniform 0;

boundaryField
{
inlet
{
type zeroGradient;
}

outlet
{
type fixedValue;
value uniform $internalField;
}

walls
{
type zeroGradient;
}

front_back
{
type empty;
}

symmetry
{
type symmetryPlane;
}
}

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

I have literally no clue on how to solve this problem.
Can anybody help me? Could it be related to something extern of the p file?

Because internalField also contains the word uniform, You are using that word twice.

Change this:

outlet
{
     type fixedValue;
     value uniform $internalField;
}

To:

outlet
{
    type fixedValue;
    value  $internalField;
}

Wow, now i feel like a stupid.
Now the simulation work like a charm.

Thanks a lot!
