Hi all,
I'm trying to use first order upwind gradient that depends on a user defined surfaceScalarField for the upwinding direction. But I have problem where the solver does not recognize my user defined surfaceScalarField, "SSF", when I select the discretization scheme in the fvSchemes file. For instance, when I want to take gradient of some volScalarField, "psi", in my solver, I put

Code:
grad(psi) Gauss upwind SSF;
in fvSchemes.

Where, as I mentioned above, "SSF" is my user defined field. If its relevant, It was initialized using:

Code:
surfaceScalarField SSF
    (
        IOobject
        (
            "SSF",
            runTime.timeName(),
            mesh,
            IOobject::NO_READ,
            IOobject::NO_WRITE
        ),
         fvc::interpolate(alpha1)
    );
When I try to run the solver, it doesn't recognize or even see that "SSF" exists as a surfaceScalarField. I receive the following error at runtime:

Code:
 request for surfaceScalarField SSF from objectRegistry region0 failed
    available objects of type surfaceScalarField are

5
(
rhoPhi
ghf
phi
nVecf
nHatf
)
I want to use my SSF surfaceScalarField but I can not.
Anyone knows how to define the SSF that would be recognized in the fvSchemes?
