[Other] very basic question about createPhi.H

feldy77 · November 22, 2011, 01:05

Hi Foamers,
I have a very basic question about createPhi.H definition

ifndef createPhi_H
#define createPhi_H
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
Info<< "Reading/calculating face flux field phi\n" << endl;
surfaceScalarField phi
(
IOobject
(
"phi",
runTime.timeName(),
mesh,
IOobject::READ_IF_PRESENT,
IOobject::AUTO_WRITE
),
linearInterpolate(hU) & mesh.Sf()
);

Everething is clear except hU field. What is it and where it is defined?
Many thanks, Yuri

My version of createPhi.H (OpenFOAM-2.0.x/src/finiteVolume/cfdTools/incompressible) just has U there, which makes sense. Which version are you refering to?

Hi Bernhard,
Thaks for your reply,
I a working with 1.7. Now follwoing the path you
mentioned I also found that the flux is computed using U.
Before I was looking at the file related to the ShallowWaterFoam solver.
I think that was the reason for confusion
