Plate Attributes: Face Radiation Coefficient

Description

Assigns a radiation coefficient to surfaces of selected plate elements.

Applicable only to nonlinear heat transfer analysis.

Models uniform heat flow via radiation through the surface of the plate to or from an ambient environment. The attribute is paired with a plate face radiation ambient temperature attribute, which together define the heat flow rate.

Different radiation coefficients can be defined on the -z and +z surfaces.

The coefficient can be scaled as a function of time and/or temperature.

Radiation coefficient attributes are load case dependent.
