PERIODIC

is assumed to apply both in the positive and neg ative directions of the distance vector. The default

value is NR=2.

Data line to deﬁne periodic symmetry of a two-dimensional cavity (TYPE=2D):

First (and only) line:

1. x-coordinate of point a (see Figure 16.5–1).

2. y-coordinate of point a.

3. x-coordinate of point b.

4. y-coordinate of point b.

5. x-component of p eriodic distance vector.

6. y-component of periodic distance vector.

Data lines to deﬁne periodic symmetry of a three-dimensional cavity (TYPE=3D):

First line:

1. x-coordinate of point a (see Figure 16.5–2).

2. y-coordinate of point a.

3. z-coordinate of point a.
