INCIDENT WAVE INTERACTION PROPERTY

9.11

INCIDENT WAVE INTERACTION PROPERTY: Deﬁne the geome tric data and ﬂuid

properties describing an incident wave.

This option deﬁnes the geometric data and ﬂuid properties used to deﬁne incident waves. Each

INCIDENT

WAVE INTERACTION option must refer to an

INCIDENT WAVE INTERACTION PROPERTY deﬁnition.

Products: ABAQUS/Standard ABAQUS/Explicit
