(a) F num = 25 (25 frequencies)
(b) F min = 0.01 (Hz)
(c) F delta = 0.01 (Hz)
(d) Water depth = 47 (Depth at offshore boundary in meters)
(e) Wave dir = Global (Use standard wave direction convention or
select Local to use STWAVE local convention as defined in
Figure 3.)
(f) Check option to Replace Old Spectra.
(g) Number of Rows: 2 (number of events to generate)
(h) Index = 175500, H = 5 m, T = 15 sec, Angle = 250 deg,

the cursor around the window and look at the top of the dialog for
numbers to display after each Cursor parameter: Freq, Angle,
and Energy. If Cursor parameter values do not appear, this
indicates that spectra have not been generated. Repeat steps provided
previously to generate spectra. If Cursor parameter values do
appear, click the Contour Options
in the upper left corner of
the Spectral Energy Dialog.
(a) Change the option, Contour between Specified Range, to
(1) Maximum Value = 1.0 (energy density)
(2) Press OK
5.
To plot frequency and directional distributions of spectra:
(a) Select Freq. Plot button.
(b) Select Dir. Plot button.
6.
When multiple input spectra are available for visualization, choose
one by selecting a time or integer from the Time Step option at top
right of the Spectral Energy Dialog or click the Data Browser
and select a Time Step.
