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.
