Description of commands 83
OUTput [tbegspc] [deltspc] < MIn >
| HR |
| DAy |
With this optional command the user indicates that for each location of the output location
set ’sname’ (see commands POINTS, CURVE, FRAME or GROUP) the 1D or 2D variance /
energy (see command SET) density spectrum (either the relative frequency or the absolute
frequency spectrum) is to be written to a data file. The name ’fname’ is required in this
command.

OUTPUT
[tbegspc]
[deltspc]
name of the set of POINTS, CURVE, FRAME or GROUP
means that 2D (frequency-direction) spectra are written to file according to the
format described in Appendix D. Note that this output file can be used for
defining boundary conditions for subsequent SWAN runs (command BOUNDSPEC).
means that 1D (frequency) spectra are written to file according to the format
described in Appendix D. Note that this output file can be used for defining
boundary conditions for subsequent SWAN runs (command BOUNDSPEC).
means that spectra are computed as function of absolute frequency (i.e. the
frequency as measured in a fixed point).
means that spectra are computed as function of relative frequency (i.e. the
frequency as measured when moving with the current).
name of the data file where the output is written to.
the user requests output at various times. If the user does not use this option,
the program will give SPECOUT output for the last time step of the computation.
begin time of the first field of the variable, the format is:
1 : ISO-notation 19870530.153000
2 : (as in HP compiler) ’30−May−87 15:30:00’
3 : (as in Lahey compiler) 05/30/87.15:30:00
4 : 15:30:00
5 : 87/05/30 15:30:00’
6 : as in WAM 8705301530
This format is installation dependent. See Implementation Manual or ask the
person who installed SWAN on your computer. Default is ISO-notation.
time interval between fields, the unit is indicated in the next option:
SEC unit seconds
MIN unit minutes
HR unit hours
DAY unit days
