INCIDENT WAVE

PRESSURE AMPLITUDE

Set this parameter equal to the name of the amplitude curve deﬁning the ﬂuid pressure time

history at the standoff point (“Am plitude curves,” Section 27.1.2 of the ABA QUS Analysis

User’s Manual). The corresponding ﬂ uid traction, if required, will be computed from the pressure

amplitude reference.

Data lines to deﬁne an incident wave:

First line:

1. Surface nam e.

2. Reference magnitude.

Repeat this data line as often as necessary to describe the loading on the surfaces due to the incident

wave. In problems involving ﬂuid-solid boundaries, both the ﬂuid surface and the solid s urface comprising

the boundar y must have an incident wave load speciﬁed, using the appropriate load type.
