Temperature Dependent Radiation Condition
Select Function of Temperature option from the Temperature Dependence drop-down list in the Radiation Condition dialog box if you want emissivity to vary as a function of temperature. You must define the function over a temperature range that is used during the analysis.
When you select Function of Temperature, the Radiation Condition dialog box expands to display the 
button along with a list of predefined functions in the Temperature Dependence area. Click to open the Function Definition dialog box along with the temperature as an independent variable.
