Hello all,

I'm studying how to implement a variable gradient boundary condition for temperature. Reading the OpenFOAM official documentation, most of the classes have no *detailed description*.

So my problem arises: how to know from which class derive my class? Of course I have a vague idea, but there is any more complete documentation about the set of classes implementing BCs?

Second question in the same post: any explanation on what is the *fvsPatchField* class? I mean, what does this "s" means?

Thanks a lot and sorry for any elementary question, but OpenFOAM documentation lacks some basic information to allow newcomers to "walk by themselves".
