27.21. The WGTD Data Record - Wave Elevation at Grids Output Duration

The WGTD data record defines the time duration and time step interval for outputting the wave elevation at the mean water surface grids around a specified structure. This data record is only applicable to time domain analyses that include wave definitions.

(1) The default value is 1 if it is not defined or not positive.

(2) The default value is the number of total time steps defined in Data Category 16: Time Integration Parameters - TINT.

(3) The default value is 1 if it is not defined or not positive.


Note:  The WGRD data record must be defined before the WGTD data record when requiring the time domain disturbed wave elevations at the wave grids.
