Hi,

Been trying to calculate the entropy field through openFOAM 5.X. My problem is a simple channel (1 inlet 1 outlet) with heated walls and air flowing.

So far, I tried to use the conclusions presented by Bruno in Entropy calculation in OpenFoam post #11

But still not beeing able to compile entropy.c. Because it was intended to openFOAM 2.2X I suppose.

So far, I changed the Make/options file to include the line:

-I$(LIB_SRC)/transportModels/compressible/lnInclude \

To include compressibleTransportModel. And now I ended up with the following error message:

entropy.C:145:62: error: binding reference of type 'Foam::fvPatchScalarField& {aka Foam::fvPatchField<double>&}' to 'const Foam::fvPatchField<double>' discards qualifiers
fvPatchScalarField& pS = S.boundaryField()[patchi];

I could include a const before fvPatchScalarField& pS but it doesn't seem right.

I have very little knowledge on programming in openFOAM. Any help would be of great value.

Thanks.

Andre

Try replacing

fvPatchScalarField& pS = S.boundaryField()[patchi];

with

fvPatchScalarField& pS = S.boundaryFieldRef()[patchi];
