*REFLECTION
17.12 *REFLECTION: Define reflection symmetries for a cavity radiation heat transfer
analysis.
This option is used to define a cavity symmetry by reflection through a line or a plane. It can be used only
following the *RADIATION SYMMETRY option.

Required parameter:
TYPE
Set TYPE=LINE to create a cavity composed of the cavity surface defined in the model and its
reflection through a line. See Figure 17.12–1. This option can be used only for two-dimensional
cases.
Set TYPE=PLANE to create a cavity composed of the cavity surface defined in the model
and its reflection through a plane. See Figure 17.12–2. This option can be used only for three-
dimensional cases.
Set TYPE=ZCONST to create a cavity composed by the cavity surface defined in the model
and its reflection through a line of constant z-coordinate. See Figure 17.12–3. This option can be
used only for axisymmetric cases.
Data line to define reflection of a two-dimensional cavity (TYPE=LINE):
First (and only) line:
1. X-coordinate of point a (see Figure 17.12–1).
2. Y-coordinate of point a.
3. X-coordinate of point b.
4. Y-coordinate of point b.
