Can somebody tell me how i can view macros in Fluent? i need to modify the wall functions to atmospheric boundary flows. When i looked at the example in DEFINE_WALL_FUNCTIONS, i realised that there are many reserved names for the variables Fluent uses. For example, UPLUS_LAM is the u+ in the laminar region.
I need to change the way Fluent defines Y plus. Instead of incorporating roughness height, i want it to use aerodynamic roughness length. And also, what is the reserved name for wall shear stress in the macros. Anybody knows?
