Hi Foamers!

I'm working on a simulation using pisoFoam, I'm using the nutkRoughWallFunction with the following parameters:

The roughness height ks is required as the input of most nut wall equations, to assure a rough wall log layer between the center of the first near-bed grid cell and the wall. In our case, the first near-bed grid cell is equal to 5-cm, ks is 10-cm, and zo is approximately 2*ks (20-cm).


FoamFile
{
version 2.0;
format ascii;
class volScalarField;
object nut;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions [0 2 -1 0 0 0 0];

internalField uniform 0;

boundaryField
{
bed
{
type nutURoughWallFunction;
Ks uniform 0.1;
Cs uniform 2;
Cmu 0.09;
kappa 0.41;
E 9.8;
roughnessFactor 1;
value $internalField;
}
topWall
{
type slip;
}
sideRight
{
type slip;
}
sideLeft
{
type slip;
}
inlet
{
type fixedValue;
value uniform 1e-06;
}
out
{
type zeroGradient;
}
}


AND I GOT THIS ERROR:

Can anyone help me to understand and solve the error, please?
