*INCIDENT WAVE PROPERTY

Data lines to define an incident wave property

First line

1. X-coordinate of ${\mathbf{x}}_{\mathbf{0}}$, the position of the incident wave standoff point.

2. Y-coordinate of ${\mathbf{x}}_{\mathbf{0}}$, the position of the incident wave standoff point.

3. Z-coordinate of ${\mathbf{x}}_{\mathbf{0}}$, the position of the incident wave standoff point.

4. X-component of ${\mathbf{v}}_{\mathbf{0}}$, the velocity of the incident wave standoff point.

5. Y-component of ${\mathbf{v}}_{\mathbf{0}}$, the velocity of the incident wave standoff point.

6. Z-component of ${\mathbf{v}}_{\mathbf{0}}$, the velocity of the incident wave standoff point.

Second line

1. X-coordinate of ${\mathbf{x}}_{\mathbf{S}}$, 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 ${\mathbf{x}}_{\mathbf{S}}$, 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 ${\mathbf{x}}_{\mathbf{S}}$, 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 ${\mathbf{x}}_{\mathbf{S}}$ to ${\mathbf{x}}_{\mathbf{0}}$ 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.
