What is Gauss linear upwind?
Hi,
i have a question concerning an existing case i didn't create by myself, but I have to use it. There's a divScheme i don't understand: div((nuEff*def(grad(U).T()))) Gauss linear upwind; I know linear is second order interpolation. I know upwind is first order interpolation. But I don't know how this one behaves and which on the argument of the other one is. Could someone tell me something like Gauus <interpolationScheme> <...>? Gauss <...> <interpolationScheme>? Thanks for your help, okroud 
You could check out the source code for it here:
Code:
/src/finiteVolume/lnInclude/linearUpwind.C 
Thanks. So you think that linear upwind is the same as linearUpwind and therefore a second Order Scheme?

I'm not completely sure. I've actually never seen anything with that particular syntax. I've seen
Code:
Gauss linear Code:
Gauss linearUpwind phi

I'd realy like to understand the mathematical background of some of the schemes by watching the sourcecode, is there any source or work where the schemes are mathematically further explained?
