The WGRD data record calculates and outputs the disturbed wave heights at the mean water surface grids around a specified structure. The data record is only applicable to time domain analyses that include wave definitions. The data record is described below:

(1) and (2) are parameter inputs of the WGRD data record that define the disturbed wave height output around the specified structure. These parameter inputs work together to determine the structure that outputs the disturbed wave height.

(3) The name of the .PAG file that imports the frequency domain database of wave elevation at the mean free surface grids. This database is used to calculate and output the sum of the incident and diffraction wave heights in the time domain analysis.
