RADIATION VIEWFACTOR: Control cavity radiation and viewfactor calculations.
This option is used to control the calcul ation of viewfactors during a cavity radiation analysis.
Product: ABAQUS/Standard
Type: History data
Level: Step
Reference:
•
“Cavity radiation,” Section 32.1.1 of the ABAQUS Analysis User’s Manual
Optional parameters:
BLOCKING
Set B LOCKING=A LL (default) to specify that full blocking checks be performed in the viewfactor
calculations.
Set BLOCKING=NO to specify that no blocking checks be performed in the viewfactor
calculations.
Set BLOCKING=PARTIAL to specify that partial blocking checks be performed in the
viewfactor calculations. The data lines are then used to specify the potential blocking surfaces.
CAVITY
Set this parameter equal to the name of the cavity for which radiation viewfactor control is being
specified. If this parameter is omitted, the specification applies to all cavities defined in the model.
OFF
Include this parameter to switch off cavity radiation effects. Cavity radiation effects can be switched
on again by a subsequent use of this option without th e OFF parameter. If this parameter is omitted,
cavity radiation is active.
RANGE
Set this parameter equal to a distance beyond which viewfactors need not be calculated because
surfaces are judged to be too far apart to “see” each other (due to blocking by other surfaces).
REFLECTION
Set REFLECTION=YES (default) to indicate that reflection must be included in the cavity radiation
calculations.
Set REFLECTION=NO to indicate that reflection is to be ignored in the cavity radiation
calculations. No reflection corresponds to the special case of black body radiation (see “Cavity
radiation,” Section 2.11.4 of the ABAQUS Theory Manual).
