*INCIDENT WAVE INTERACTION
9.10 *INCIDENT WAVE INTERACTION: Define incident wave loading for a blast or
scattering load on a surface.
This option is used to apply incident wave loading. The *INCIDENT WAVE INTERACTION PROPERTY
option must be used in conjunction with the *INCIDENT WAVEINTERACTION option. If the incident
wave field includes a reflection off a plane outside the boundaries of the mesh, this effect can be modele dw ith
the *INCIDENT WAVE REFLECTION option.

Required parameter:
PROPERTY
Set this parameter equal to the name of the *INCIDENT WAVE INTERACTION PROPERTY
option defining the incident wave field.
Required, mutually exclusive parameters:
ACCELERATIONAMPLITUDE
Set this parameter equal to the name of the amplitude curvedefining the fluid particle acceleration
time history at the standoff point (“Amplitude curves,” Section 27.1.2of the ABAQUS A nalysis
User’s Manual). This amplitude curve will be used to compute the fluid traction only: a solid
surface requiring a pressure load cannot be specified on the data line of an *INCIDENT WAVE
INTERACTION option if the ACCELERATIONAMPLITUDE parameter is used.
This parameter is valid only for planar incident waves using the *INCIDENT WAVE
INTERACTION PROPERTY, TYPE=PLANE option. Reflected loads, using the *INCIDENT
WAVE REFLECTION option, are not permitted in this case.
