INCIDENT WAVE INTERACTION

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.

UNDEX

Include this parameter to deﬁne a spherical incident wave using the

UNDEX CHARGE

PROPERTY option. This parameter is valid on ly for spherical incident waves using the

INCIDENT WAVE INTERACTION PROPERTY, TYPE =SPHERE option.

Data line to deﬁne an incident wave:

First (and only) line:

1. Surface nam e.

2. The node number or set name of the source node.

3. The node number or set na me of the standoff node.

4. Reference magnitude.
