*INCIDENT WAVE REFLECTION
9.13 *INCIDENT WAVE REFLECTION: Define the reflection load on a surface caused by
incident wave fields.
This option is used to define reflected incident wave fields. It must be used in conjunction with the
*INCIDENT WAVE INTERACTION option (preferred interface for applying incident wave loading) or the
*INCIDENT WAVE option (alternative interface). The alternative interface will be removed in a subsequent
release.

There are no parameters associated with this option.
Data lines to define an incident wave reflection:
First line:
1. Distance from the source point to the first reflecting plane.
2. X-direction cosine of the normal to the reflecting plane, pointing away from the source point.
3. Y-direction cosine of the normal to the reflecting plane, pointing away from the source point.
4. Z-direction cosine of the normal to the reflecting plane, pointing away from the source point.
5. Reflection coefficient.
Repeat this data line as often as necessary to describe the planes that reflect the incident wave.
