Correctly defining the fields of mean wave parameters in shel.inp file (WW3)

[BilalYasirAlvi]

Hello

I am having trouble in defining the shel.inp file correctly for WW3. For type 1 (Fields of mean wave parameters), I have tried both the F/T flag (as given in the manual) and Namelists option, but the file is not running correctly.

I have never used the F/T flag option before so I find it hard to get it right. I have seen the issues on WW3 forum and they recommend namelists option v6.07 onwards. But, in my experience with COAWST so far, the traditional options are more appropriate and same has been defined in the manual as well so I want to understand this F/T option.

If I only need the group 2 (Standard mean wave parameters) then should I just apply T for all its parameters and comment out all other groups?

My shel.inp file is as follows:

$ -------------------------------------------------------------------- $
$ WAVEWATCH III shell input file $
$ -------------------------------------------------------------------- $
$ Define input to be used with F/T/C flag for use or nor or coupling and
$ T/F flag for definition as a homogeneous field.
$
$ Include ice and mud parameters only if IC1/2/3/4 used :
F F Water levels
F F Currents
T F Winds
F F Ice concentrations
F Assimilation data : Mean parameters
F Assimilation data : 1-D spectra
F Assimilation data : 2-D spectra
$
$ Time frame of calculations ----------------------------------------- $
$ - Starting time in yyyymmdd hhmmss format.
$ - Ending time in yyyymmdd hhmmss format.

$
$ Define output data ------------------------------------------------- $
$
$ Define output server mode. This is used only in the parallel version
$ of the model. To keep the input file consistent, it is always needed.
$ IOSTYP = 1 is generally recommended. IOSTYP > 2 may be more efficient
$ for massively parallel computations. Only IOSTYP = 0 requires a true
$ parallel file system like GPFS.
$
$ IOSTYP = 0 : No data server processes, direct access output from
$ each process (requires true parallel file system).
$ 1 : No data server process. All output for each type
$ performed by process that performs computations too.
$ 2 : Last process is reserved for all output, and does no
$ computing.
$ 3 : Multiple dedicated output processes.
$
1
$
$ Five output types are available (see below). All output types share
$ a similar format for the first input line:
$ - first time in yyyymmdd hhmmss format, output interval (s), and
$ last time in yyyymmdd hhmmss format (all integers).
$ Output is disabled by setting the output interval to 0.
$
$ ------------------------------------------------------------------- $
$
$ Type 1 : Fields of mean wave parameters
$ Standard line and line with logical flags to activate output
$ fields as defined in section 2.4 of the manual. The logical
$ flags are not supplied if no output is requested. The logical
$ flags can be placed on multiple consecutive lines. However,
$ the total number and order of the logical flags is fixed.
$ The raw data file is out_grd.ww3,
$ see w3iogo.ftn for additional doc.

$ NOTE : Spaces may be included in the name, but this is not

$ plots spectra and source terms, and will make it more
$ difficult to use point names in data files.
