Dear Foamers,

I would like to access the scalarField of the roughness height Ks from a patch field of nut. By now I get the fvPatchScalarField

const fvPatchScalarField& nutField = bottomFvPatch.lookupPatchField<volScalarField, scalar>("nut");
Info << nutField << endl;

This results in the following output:

type            nutRoughWallFunction;
Cmu             0.09;
kappa           0.41;
E               9.8;
Cs              uniform 0.5;
Ks              uniform 0.001;
value           nonuniform List<scalar> 
350
(
0.000654725
0.000654725
0.000654725
...

Now I would like to continue working with the Ks-field, but somehow I don't get it extracted. I'm thinking of something like

localKs = nutField.lookupEntry("Ks");

Any hints anyone? Maybe it's possible to cast the fvPatchScalarField into a dictionary?

Thanks in advance!
Florian
