*INCIDENT WAVE PROPERTY

Define the geometric data describing an incident wave.

The preferred interface for defining the geometric data for an incident wave is the INCIDENT WAVE INTERACTION PROPERTY option used in conjunction with the INCIDENT WAVE INTERACTION option. The alternative interface uses the INCIDENT WAVE PROPERTY option to define the geometric data for incident waves.

Each INCIDENT WAVE option must refer to an INCIDENT WAVE PROPERTY definition. The INCIDENT WAVE PROPERTY option must be followed by the INCIDENT WAVE FLUID PROPERTY option, which defines the fluid properties used in the incident wave loading.

Required parameters

NAME

Set this parameter equal to a label that will be used to refer to the incident wave property in the INCIDENT WAVE option.

Optional parameters

TYPE

Set TYPE=PLANE (default) to specify a planar incident wave.

Set TYPE=SPHERE to specify a spherical incident wave.

Data lines to define an incident wave property

First line

  1. X-coordinate of x0, the position of the incident wave standoff point.

  2. Y-coordinate of x0, the position of the incident wave standoff point.

  3. Z-coordinate of x0, the position of the incident wave standoff point.

  4. X-component of v0, the velocity of the incident wave standoff point.

  5. Y-component of v0, the velocity of the incident wave standoff point.

  6. Z-component of v0, the velocity of the incident wave standoff point.

Second line

  1. X-coordinate of xS, the position of the incident wave source point. Alternatively, specify the name of an AMPLITUDE definition describing the time history of this coordinate.

  2. Y-coordinate of xS, the position of the incident wave source point. Alternatively, specify the name of an AMPLITUDE definition describing the time history of this coordinate.

  3. Z-coordinate of xS, the position of the incident wave source point. Alternatively, specify the name of an AMPLITUDE definition describing the time history of this coordinate.

If TYPE=PLANE, the vector from xS to x0 defines the direction of the incoming wave; the distance between the two points is unimportant. For incident wave loads using bubble amplitudes, the source positions defined by the user with the INCIDENT WAVE PROPERTY option are interpreted as the initial positions of the source.
