GEOM

Choice of geometry:

0

 — 

Planar (default).

1

 — 

Axisymmetric

NDIV

Number of divisions for axisymmetric geometry (that is, the number of circumferential segments). Default is 20. There is no maximum limit if HIDOPT = 0; the maximum is 90 if HIDOPT = 1.

For more information, see View Factors of Axisymmetric Bodies in the Mechanical APDL Theory Reference.

HIDOPT

Viewing option:

0

 — 

Hidden (default).

1

 — 

Non-hidden

NZONE

Number of zones (that is, the number of rays emanating from a surface) for view factor calculation. Default is 200. Maximum is 1000.

Command Default

V2DOPT allows you to select options for 2-D view factor calculation. The geometry type can be set to either 2-D plane or axisymmetric (defaults to plane). You can also define the number of divisions (defaults to 20) for an axisymmetric geometry. This command also allows you to select either hidden or non-hidden viewing option (defaults to hidden) and the number of zones for view factor calculation (defaults to 200).

For 2-D view factor calculations, the ray-emanation method is used.
