*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.

Products: Abaqus/Standard  Abaqus/Explicit  Abaqus/CAE  

Type: Model data in Abaqus/Standard; History data in Abaqus/Explicit

Level: Part,  Part instance,  Assembly,  Model in Abaqus/Standard; Step in Abaqus/Explicit  

Abaqus/CAE: Interaction module

There are no parameters associated with this option.

Data lines to define surface constants for radiative heat transfer: 

First line:

  1. Emissivity, .

  2. Emissivity, .

Second line:

  1. Effective view factor, F.

  2. Gap clearance, d.

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