I am wondering how does fluent treat properties (u,v,w,P,T) at boundaries? For example I know at an outflow boundary condition du/dx=0, dT/dx=0 what about the other properties? At pressure inlet you specify a presssure vaalue and so how are u,v,w and T treated? I need to understand the mathematics of each boundary condition in Fluent, what is the mathematical form of the boundary conditions for each governing equation? I searched the manual but did not find an answer. So please if anyone knows anything in this regard, let me know. Thanx
