$
$ Frequency increment factor and first frequency (Hz) ---------------- $
$ number of frequencies (wavenumbers) and directions, relative offset
$ of first direction in terms of the directional increment [-0.5,0.5].
$ In versions 1.18 and 2.22 of the model this value was by definiton 0,
$ it is added to mitigate the GSE for a first order scheme. Note that
$ this factor is IGNORED in the print plots in ww3_outp.
$

$
$ Set model flags ---------------------------------------------------- $
$ - FLDRY Dry run (input/output only, no calculation).
$ - FLCX, FLCY Activate X and Y component of propagation.
$ - FLCTH, FLCK Activate direction and wavenumber shifts.
$ - FLSOU Activate source terms.

$
$ Start of namelist input section ------------------------------------ $
$ Starting with WAVEWATCH III version 2.00, the tunable parameters
$ for source terms, propagation schemes, and numerics are read using
$ namelists. Any namelist found in the folowing sections up to the
$ end-of-section identifier string (see below) is temporarily written
$ to ww3_grid.scratch, and read from there if necessary. Namelists
$ not needed for the given switch settings will be skipped
$ automatically, and the order of the namelists is immaterial.
$ As an example, namelist input to change SWELLF and ZWND in the
$ Tolman and Chalikov input would be

$ If sub-grid information is available as indicated by FLAGTR above,

$ be supplied. First the location and format of the data is defined
$ by (as above) :
$ - Unit number of file (can be 10, and/or identical to bottom depth
$ unit), scale factor for fractional obstruction, IDLA, IDFM,
$ format for formatted read, FROM and filename

$ *** NOTE if this unit number is the same as the previous bottom
$ depth unit number, it is assumed that this is the same file
$ without further checks. ***
$
$ If the above unit number equals 10, the bottom data is read from
$ this file and follows below (no intermediate comment lines allowed,
$ except between the two fields).

$ Input boundary points from segment data ( FROM = PART ) ------------ $
$ An unlimited number of lines identifying points at which input
$ boundary conditions are to be defined. If the actual input data is
$ not defined in the actual wave model run, the initial conditions
$ will be applied as constant boundary conditions. Each line contains:
$ Discrete grid counters (IX,IY) of the active point and a
$ connect flag. If this flag is true, and the present and previous
$ point are on a grid line or diagonal, all intermediate points
$ are also defined as boundary points.

$ Output boundary points --------------------------------------------- $
$ Output boundary points are defined as a number of straight lines,
$ defined by its starting point (X0,Y0), increments (DX,DY) and number
$ of points. A negative number of points starts a new output file.
$ Note that this data is only generated if requested by the actual
$ program. Example again for spherical grid in degrees. Note, these do
$ not need to be defined for data transfer between grids in the multi
$ grid driver.
