Hello

Simple-ish question, this. I'm writing a boundary condition for reactingFoam. Typically, when I want to get values on said boundary, I do something like this,

const fvPatchField<scalar>& p = patch().lookupPatchField<volScalarField, scalar>("p");
const fvPatchField<vector>& U = patch().lookupPatchField<volVectorField, vector>("U");

Which works fine (see endless examples in $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived).

I can't seem use this method to get the specific heat, Cp. If I try I get the error,

--> FOAM FATAL ERROR: 
    request for volScalarField Cp from objectRegistry region0 failed
    available objects of type volScalarField are

followed by a list of all the variables I can access this way. Cp is not in said list.

Does anyone know how can I get Cp (and by extension other thermophysical data) on a boundary patch in this sort of context?

Many thanks in advance
