VIEW

View Factor Definition

Description: Defines radiation cavity and shadowing for radiation view factor calculations.

Format:

Example:

Field	Definition	Type	Default
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.	Character	BOTH

Remarks:

1. VIEW must be referenced by CHBDYG or CHBDYP elements to be used.
2. 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.
3. SHADE references shadowing for CHBDYi elements participating in a radiation cavity, the VIEW calculation can involve shadowing.
