*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 SYMMETRYoption.

Product: ABAQUS/Standard

Type: History data

Level: Step

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. T his 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 b e used only for three-

dimensional cases.

Set TYPE=ZCONST to create a cavity composed by the cavity surface deﬁned inthe m odel

and its reﬂection through a line of constant z-coordinate. See Figure 17.12–3. This option ca n 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.
