8.3.4 Density as a Profile Function of Temperature

If you are modeling a problem that involves heat transfer, you can define the density as a function of temperature. Three types of functions are available:

For one of the these methods, select piecewise-linear, piecewise-polynomial, or polynomial in the Density drop-down list. You can enter the data pairs ( $T_n , \rho_n$), ranges and coefficients, or coefficients that describe these functions using the Materials panel, as described in Section  8.2.
