EMIS

EMIS, MAT, EVALU
Specifies emissivity as a material property for the Radiation Matrix method.

AUX12: Radiation Matrix Method

MAT: Material number associated with this emissivity (500 maximum). Defaults to 1.
EVALU: Emissivity for this material (0.0 < EVALU 1.0). Enter a very small number for zero.

Command Default

Since there is no command default value for emissivity, you must issue EMIS to specify it. Otherwise, an error message appears. If you issue EMIS without defining a numerical value, emissivity defaults to 0.

Notes

Specifies emissivity as a material property for the Radiation Matrix method. This material property can then be associated with each element.
