*WAVE

5. y-direction cosine deﬁningthe direction of the vector (the directio nof tr avel for this wave

component). This com ponent is not needed in two-dimensional cases.

Repeat this data line as oftenas necessar y to deﬁne multiplewave trains; one line per wave component.

Data line to deﬁne gridded wave data (TYPE=GRIDDED):

First (and only) line:

1. x-coordinate of the origin of the wave data grid.

2. y-coordinate of the origin of the wave data grid.

3. z-coordinate of the origin of the wave data grid.

4. Directioncosine between the local x-axis of the wave data grid and the global x-axis. (Plusor

minus one for two-dimensional analysis.)

5. Directioncosine between the local x-axis of the wave data grid and the global y-axis. (Zero

for two-dimensional analysis.)

Data line to deﬁne frequency versus wave amplitude data for stochasticuser wave theory

(TYPE=USER):

First line:

1. Frequency(in cycles per time, for stochastic analysis only).

2. Wave amplitude.

Repeat this data line as often as necessary to deﬁne the wavespectr um. These data pairs are passed

into user subroutine UWAVE. They are not used otherwise byABAQUS/Aqua.
