Ok it works for mu, rho, alpha and psi using function objects and chtMRSF.

I am trying to implement the output of Cp for chtMultiRegionSimpleFoam.
I tried to do it in analogy to rho adding the following to createFluidFields.H

    PtrList<volScalarField> CpFluid(fluidRegions.size());


        Info<< "    Adding to thermoFluid\n" << endl;

        thermoFluid.set
        (
            i,
            CpThermo::New(fluidRegions[i]).ptr()
        );

    Info<< "    Adding to CpFluid\n" << endl;
    CpFluid.set
    (
        i,
            new volScalarField cp_output
        (
            IOobject
            (
            "Cp",
            runTime.timeName(),
            mesh,
            IOobject::NO_READ,
            IOobject::AUTO_WRITE
            ),
            thermoFluid[i].Cp()
        )
    );

and to setRegionFluidFields

    volScalarField& Cp = CpFluid[i];

When compiling I get the error message

In file included from chtMultiRegionSimpleFoamMuCp.C:71:0:
fluid/setRegionFluidFields.H:7:21: warning: unused variable ‘Cp’ [-Wunused-variable]
     volScalarField& Cp = CpFluid[i];

Could you help me with that one?

If I want to use writeObjects functions , but some properties are not available, such as kappa Cp. Should I build volScalarField kappa/Cp in creatFields.H then use writeObjects?

Or are there other methods to present kappa Cp in post-processing? I want to see the relationship between T and Cp/kappa. Thank you.
