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.

I also want to add power law factor n and consistancy factor k but i cant add in CFX. please any one tell that how i add, n and k to define fluid. thanks

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

[ghorrocks]

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.

here i have the same qustion? for H-B model (pulp suspension), wich consistency is 10%, I want to kow the pow low index n , k, max and min shear strain rate ..,
