*GAP RADIATION

Introduce heat radiation between surfaces.

This option is used to provide radiative heat transfer between closely adjacent surfaces. It must be used in conjunction with the SURFACE INTERACTION option or in an Abaqus/Standard analysis with the GAP option.

Data lines to define surface constants for radiative heat transfer

First line

  1. Emissivity, ϵA.

  2. Emissivity, ϵB.

Second line

  1. Effective view factor, F. (0≤F≤1)

  2. Gap clearance, d.

Repeat this data line as often as necessary to define the dependence of the view factor on gap clearance.
