CFX non newtonian power law fluid
 
I do not know how I will add power law fluid especilly n< 1 in cfx ..I tried to add n<1 fluids but it gives mistake..and for power law fluid the unit of the K is kg.s^n/m^2 also I did not add K.

Hi Javed
I have the same problem. Please can you help me to set a Non-Newtonian model?

The documentation lists the available non-Newtonian models. These models have some restictions on what is allowable - you may be trying to apply a model which is not allowed, and therefore cannot be done on CFX.
