Re: [swanmodel-users] Wind file specification

[Sandhya K G <san...@in...>]

Dear Clayton and others,

My problem is solved. I gave 

READINP WIND 1 SERIES 'windlist_may08_dec08' 3 0 FORMAT '(361F15.4)'

whereas my 'windlist_may08_dec08' read as

./wind/OID05010000050100001.dat
./wind/OID05010000050103001.dat
.............
.............
etc.

Earlier my problem was that the directory in which wind was kept was very different from the working directory (in which SWAN was being run). Then I was specifying the whole path to that directory in my wind file name 'windlist_may08_dec08'. Later I understood that there is a restriction of 36 characters for the file names in SWAN. This is not only for the file name, but also for the path in the 'windlist_may08_dec08' file. When I gave a long path like '/gpfs1/osf/data/wind_data/Karwar/Forecast/2008' the program was reading only upto 36 characters of the path, and hence it was going wrong. When I specified the path within 36 characters, it worked fine.

But still I want to know if I can change this restriction of 36 characters. Suppose I want to use 50 characters for the file names (or path). How to do it? 
Anyone got a clue???

Hi Sandhya,

I am not too sure about this one, but SWAN may require that you specify the path to 'windlist' and the wind files relative to the swan working directory.

For example, if your swan working directory is /gpfs1/osf/swan, try
READINP WIND 1 SERIES '../wind/windlist' 3 0 FORMAT '(361F15.4)'

I don't know if this will work.  In my work I usually store all the wind data in a single, but I access it in a similar way to what I just explained.  Probably worth a try anyway.

Cheers,

Dear All,

I have wind files in a directory called 'wind', whose path is /gpfs1/osf/wind
I am giving a time series wind. The filenames of the individual time steps are mentioned in a file called 'windlist', which is also present in the
/gpfs1/osf/wind  directory.
In my .swn file, I mention the wind as
READINP WIND 1 SERIES '/gpfs1/osf/wind/windlist' 3 0 FORMAT '(361F15.4)'

The model fails to run. If I keep all the wind files as well as the file 'windlist' in the working directory (directory in which .swn file is present) then the same model runs with the change in the line
READINP WIND 1 SERIES 'windlist' 3 0 FORMAT '(361F15.4)'

Is there any limitation for SWAN that the input file such as wind, bottom file... should be present in the same directory as the directory in which .swn is present?
