ABAQUS Keywords Reference Manual  

*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  

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

Level: Part  Part Instance  Assembly  Model in ABAQUS/Standard; Step in ABAQUS/Explicit

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 viewfactor, .

  2. Gap clearance, .

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