K Omega UDF

I have noticed similar problems posted in other threads but without being resolved, apologies if I have missed another thread where this has been answered.
I am writing a UDF involving the K-omega model, as written in the Fluent 6 manual, however to calculate the turbulent viscosity I need the strain rate magnitude S and the blending function F2.
For S, I think I can use C_STRAIN_RATE_MAG(c,t)
although I am unsure if there is a variable for the blending function, none is listed in the UDF manual...does anyone know of one?
failing that, does anyone know how the variable function of y, the distance to the next surface, is C_WALL_DIST(c,t) what I am looking for?
Thanks in advance for your help
