Is this the correct setup? NonNewtonian fluent Problem
Problem: You have a thickened (nonNewtonian) fluid passing through a water bottle top, where you know the initial pressure is vacuum (0kpa) and the a lab results gives you a flow rate of say 0.000779kg/s and the static pressure drop was seen as 10kPa with laminar flow. (assuming model and mesh is done and fluent set up is only needed)
General:Pressure based, Absolute and steady Models: Only viscous (Laminar) Material: fluid is almost like water, copy water poperties and change viscosity to nonNewtonian power law and add parameters Cell Zone conditions: Change it to you nonNewtonian fluid Boundary conditions:Set operation conditions to 0pa Define inlet as Massflowinlet at 0.000779kg/s Define Outlet and Outflow Define interior and walls Solution methods: Use Simple Solution controls: Change nothing Solution Initialization: Hybrid with 10 steps, initialize Run Calculation: run with 250 iterations and what for convergence Wala take results???? Is this correct or have I missed something 
Bump, Please help :/

Also like to add I am getting a shear rate of crazy amount from a range of 2010,000 1/s

Hi,
Your set up looks fine. I suggest going to monitors and setting the residuals to atleast 1e5 for better precision. As for the shear rate, where did you arrive at numbers as big as 2010,000 1/s? I generally give small numbers of the order 0.01. BB 
I meant strain rate... Sorry somehow I was must have misread it... but for my Wall Shear stress it is around 0 (possible very very small) to 43pa.. Btw thank you for the reply, what I am trying to find is Strain and Shear rate range to determine if the simulation is viable though I am not sure if I am using the right methods to do so.. I am just using Contours and using the range they give me. :)

Yielded and unyielded region in viscoplastic flluid
Hey Everyone!
I'm unable to plot yielded and unyielded region for a flow of viscoplastic fluid in a square enclosure. Help me I'm stuck. Thanks
