I posted a longer version of this a couple of weeks ago, but will post a simplified version of it again. Any comments would be greatly appreciated.
---------------------------------------------------------------------------
Can anyone point me to a general discussion, complete with a detailed description, of upwinding, streamline and cross wind diffusion and how they are implemented using the COMSOL functions? I'm not interested in just the code, but a detailed derivation and rationale for why the code is written as it is. ... I finally figured out how to manually convert the PDE (strong) form to weak form, but functions like test(), up(), down() ,and parameters like dnx, udy, etc. are not clearly described in COMSOL documention...

Any info anyone has on this would be greatly appreciated. Thx.
