| IVIEW
|
Identification number.
|
Integer > 0
|
|
| ICAVITY
|
Cavity identification number for grouping the radiant exchange faces of
CHBDYi elements.
|
Integer > 0
|
|
| SHADE
|
Shadowing flag for the face of CHBDYi element. One of the following characters variables: NONE, KSHD, KBSHD, BOTH.
| NONE
|
The face can neither shade nor be shaded by other faces.
|
| KSHD
|
The the face can shade other faces.
|
| KBSHD
|
The face can be shaded by other faces.
|
| BOTH
|
The face can both shade and be shaded by other faces.

Remarks:
- VIEW must be referenced by
CHBDYG or
CHBDYP elements to be used.
- ICAVITY references the cavity to which the face of the CHBDYi element belongs; a zero or blank value indicates this face does not participate in a cavity.
- SHADE references shadowing for CHBDYi elements participating in a radiation cavity, the VIEW calculation can involve shadowing.
