Specifying latent heat data

A material's latent heat models large changes in internal energy during phase change of the material. The latent heat is assumed to be released over a range of temperatures from a lower (solidus) temperature to an upper (liquidus) temperature.

Context:

If the phase change occurs within a known temperature range, you can enter the solidus and liquidus temperatures directly in the Edit Material dialog box. Otherwise you must model the effect with a user subroutine. See Latent heat, for more information.

  1. From the menu bar in the Edit Material dialog box, select ThermalLatent Heat.

    (For information on displaying the Edit Material dialog box, see Creating or editing a material.)

  2. Enter the following data in the Data table:

    Latent Heat

    Latent heat per unit mass. (Units of JM−1.)

    Solidus Temp

    Low end of the temperature range within which the phase changes occurs.

    Liquidus Temp

    High end of the temperature range within which the phase changes occurs.

    For detailed information on how to enter data, see Entering tabular data.

  3. Click OK to close the Edit Material dialog box. Alternatively, you can select another material behavior to define from the menus in the Edit Material dialog box (see Browsing and modifying material behaviors, for more information).
