33.4.14 Power Law Dialog Box

The Power Law dialog box allows you to set the coefficients for the power law for viscosity. This dialog box will open when you select power-law in the drop-down list next to Viscosity in the Create/Edit Materials dialog box. See Section  8.4.2 for details about the items below.

Controls

Methods   contains options for selecting the Two Coefficient Method or the Three Coefficient Method.

B   sets the coefficient $B$ in Equation  8.4-7 in SI units. This input will appear if you select the Two Coefficient Method.

Reference Viscosity   sets the reference viscosity $\mu_0$ in Equation  8.4-8. This input will appear if you select the Three Coefficient Method.

Reference Temperature   sets the reference temperature $T_0$ in Equation  8.4-8. This input will appear if you select the Three Coefficient Method.

Temperature Exponent   sets the temperature exponent $n$ in Equation  8.4-7 or 8.4-8, depending on your Method selection. If you are using the Two Coefficient Method, this input must be in SI units.
