error while running model as saving output w.r. to ntimes

[tara]

Hello ROMS community,

I am getting one error but I am not able to understand what this error says. can anyone suggest the meaning of this kind error and the probable solution.

I am attaching the ncdump information of the error associated files as well as the log file too. Error is under mentioned--------*************************************************************************************************************************

It says the error is in defining an attribute for variable ntimes in file ...oceanhis_0001.nc. Nothing to do with the forcing files. One of my output files starts the variables list with:

Code: Select all

	int ntimes ;
		ntimes:long_name = "number of long time-steps" ;

I don't know what went wrong in your case - did you fill your filesystem quota?

[tara]

Yes, kate I checked as per your clue but I have still 890 GB left in my output destination, I also tried by using different DT as well as different ntimes but nothing is resolving this issue. Is there any other mistake I am making.


Thanks & Regards--

The first thing I notice is that since the history file is the very first output ROMS attempts to create, inability to create the file can be a permission problem. ROMS gives the absolute path to the file as: /Land/tanuja_exp_27_onwards_results_backup/output... so is this a directory that exists, and for which you have UNIX write permission?

Second thing is that the error complains about an attribute called "interpolate-land/ROMS_style/svstr..." but no such attribute exists in any ROMS code. This string is part of the path to your files, i.e. the file names themselves. It's a total guess at your problem, but it might be worth shortening your directory path and file names. Also, I suggest avoiding any reserved characters (%,#... and spaces) that might be misinterpreted in the ROMS Fortran.

Remember, you can use relative paths (without a leading /) in the ocean.in file. That will shorten the strings being processed by ROMS, if indeed that is the problem (it may well not be).
