Hello Foamers,

I was looking through a tutorial page 110ish on changing boundaries, or modifying them for the files inside OpenFOAM-v1806/src/finiteVolume/fields/fvPatchFields/derived/totalTemperature/

and one of the things I came across in the convectiveHeatFluxFvPatchScalarField.C file was this line (113) for the gradient()?

gradient() = h.value() / k.value() * (Tsur.value() - T);

To compile this folder just use sudo bash and then wmake. This was for OpenFOAM 6?

I attached the complete source already compiled. convectiveHeatFlux.zip

Actually, the function

gradient()

is the gradient of the function projected on the normal face to the patch : if f is a scalar, grad(f) is a vector then n.grad(f) is a scalar.

Cheers,

Thanks! That part I do understand, it's more of a question about what class or C++ file this function is in. I guess it's an overloaded function with the parenthesis operator but I've never seen a function call made like this in C++ so I'm not sure how this is capable?
