CFD Online Discussion Forums - Accessing an entry from an fvPatchScalarField

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

Code:

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

Info << nutField << endl;

This results in the following output:

Code:

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

Code:

localKs = nutField.lookupEntry("Ks");

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

Thanks in advance!
