Heat transfer analysis in fluent
 
Hi,

I'm doing my m.tech project in Fluent.(transient condition)

A non-newtonian fluid is entering into the mold core and cavity thru runner and it is getting filled in the core and cavity. The filling time for the fluid is 4.2sec, at a flow flow rate of0.00327kg/m^3.

My continuity equation is not converging. I have given a time step of 0.001sec.

Can anyone tell me how to fill the non-newtonian power law dialog box.
I dont know how to give the consistency index, minimum viscosity limit and maximum viscosiy limit. My fluid is polystyrene entering at 513K and its power law is 0.27.
