Emissivity Model

Analysis > Emissivity Model

This panel is used to specify an ideal grey-surface emissivity for radiation modeling. This is only applicable to use in Radiation Surface panel for defining radiation on faces.

Description

  • Type
    The emissivity model can be of the following types:
    • Constant

      This option is used to specify a constant value of emissivity. The default is Black body emissivity of 1.0.

    • Piecewise Linear

      This option is used to specify the variation of emissivity as a function of Temperature. The table can be specified or imported from a text file using the Create button in the panel.

  • Multiplier Function

    A multiplier function can be used with specify a time varying emissivity.
