*INCIDENT WAVE REFLECTION

9.13 *INCIDENT WAVEREFLECTION: 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 interfacefor applying incident wave loading) or the

*INCIDENT WAVE option(alternative interface). Thealternative interface will be removed in a subsequent

release.

Products: ABAQUS/Standard ABAQUS/Explicit

There are no parameters associated with this option.

Data lines to deﬁne an incident wave reﬂection:

First line:

1. Distancefrom the source point to the ﬁrst reﬂecting plane.

2. X-direction cosine of the normal to the reﬂectingplane, pointing away from the source point.

3. Y-direction cosine of the normal to the reﬂectingplane, pointing away from the source point.

4. Z-direction cosine of the normal to the reﬂectingplane, pointing away from the source point.

5. Reﬂectioncoefﬁcient.

Repeat this data line as often as necessary to describe the planes that reﬂect the incident wave.
