*WAVE:

Define gravity waves for use in immersed structure calculations.

This option is used to define gravity waves for use in applying loads.

Optional parameters:

INPUT

Set this parameter equal to the name of the alternate input file containing the data lines for this
option. See “Input syntax rules,” Section 1.2.1 of the ABAQUS Analysis User’s Manual, for the
syntax of such file names. If this parameter is omitted, it is assumed that the data follow the keyword
line.

TYPE

Set TYPE=STOKES (default) to use Stokes fifth-order wave theory.

Set TYPE=AIRY to use Airy (linearized) wave theory.
Set TYPE=GRIDDED to use gridded data to define the fluid particle velocities, accelerations,

free surface elevation, and dynamic pressure.

Set TYPE=USER to use user subroutine UWAVE to define the fluid particle velocities,

accelerations, free surface elevation, and dynamic pressure and to specify when to update the
intermediate configuration for stochastic analysis.

Optional parameter for TYPE=AIRY:

WAVE PERIOD

Include this parameter to indicate that the second field in the data line specifies the wave period,

. If this parameter is omitted, the second field in the data line specifies the wavelength,

.

Required parameter for TYPE=GRIDDED:

DATA FILE

Set this parameter equal to the name of the file containing the gridded data. The file must be
a sequential, binary-format file containing records in the format described in “ABAQUS/Aqua
analysis,” Section 6.10.1 of the ABAQUS Analysis User’s Manual.
