Non-newtonian fluid flow

I'm simulating the turbulent flow of a non-Newtonian fluid in a pipe using Fluent.
I have some doubts related with the way as Fluent solve the complete set of equations:
1. As the dynamic viscosity is introduced as a function of shear rate/strain rate in an UDF, where can I find the way as Fluent solve the set of equations? Is the same way as for Newtonian fluids?
2. If the low-Re k-e turbulence model is enable: what happens when I enable the non-Newtonian modification for Lam-Bremhorst model? "/define models viscous turbulence-expert non-newtonian-mnodification?"
3. How can the low-Re k-e turbulence model implemented in Fluent be modified?
I hope someone can help me...
