Non-Newtonian Fluid dialog box (Flow/ESC/Multiphysics)

Group name
Name	Specifies a meaningful name for the non-Newtonian modeling object.
Label	Specifies a unique numeric identifier for the non-Newtonian modeling object.
Description	Specifies a meaningful description for the non-Newtonian modeling object.
Fluid Material
Affected Fluid Material	Modifies the selected material with the non-Newtonian fluid properties specified.Select a fluid material from the list of materials, or click Choose material to define a new material.
Non-Newtonian Model
Type	Controls the model used to describe the non-Newtonian fluid.Power Law models fluids with dilatant, pseudo-plastic, and similar behaviors.Herschel-Bulkley models fluids with Bingham, viscoplastic, and similar behaviors.Carreau models fluids that behaves as Newtonian at low shear rate and non-Newtonian for high shear rates.

Power Law type options

Additional Fluid Properties
Consistency Index [Pa-s^n]	Defines the value of the consistency index K obtained from experimental or reference material.
Power Law Index	Defines the power index n used in the model.A value of n=1 models Newtonian fluids.A value greater than 1 models a shear-thickening (dilatant) fluids.A value less than 1 models shear-thinning (pseudoplastic) fluids.
Reference Temperature	Set the reference temperature To.To define a temperature independent material, set a value of 0.
Minimum Viscosity	Defines the minimum value at which the viscosity is calculated using the power law model. Viscosity values that are lower than the specified minimum viscosity μmin are set to this value.
Maximum Viscosity	Defines the maximum value at which the viscosity is calculated using the power law model. Viscosity values higher than the specified minimum viscosity μmax are set to this value.

Herschel-Bulckley type options

Additional Fluid Properties
Power Law Index	Defines the power index n used in the model.
Yield Stress	Defines the value of yield stress τ0.
Consistency Index [Pa-s^n]	Defines the value of the consistency index K.
Yield Viscosity	Defines the yield viscosity μ0, also called plastic viscosity.

Carreau type options

Additional Fluid Properties
Time Constant	Defines the value of the time constant λ.
Power Law Index	Defines the power index n used in the model.
Reference Temperature	Set the reference temperature To.To define a temperature independent material, set a value of 0.
