Wall Treatment of User defined Turbulence Model
 
Hi,

I am running calculations with my own turbulence model with UDS(2 eqns). Regarding the near-wall treatments, in Fluent User's Guide it is say that all turbulence models have the near-wall treatments, e.g. standard wall functions or enhanced wall treatment, and wall functions are also applied to UDS transport equations.

My question is how to resolve viscous-affected region of the boundary layer by this user-defined turbulence model? Is it possible to integrate all the way to the wall without wall functions?

I'd appreciate your help. Thanks in advance.
