Writing history files - **** Vs. 0001

[jmcgovern]

Hi All,

When I set up my run to write out data hourly to history files, with a new file to cover every 24 hours, I get one file ocean_his_****.nc on the server, which keeps on getting overwritten, so I end up with only 1 file. When I copy it from the server, it shows up as ocean_his_____.nc.

I have scoured the forum and manual but there is no reference to this type of problem, that I can see.

Thanks,
Joe

This string is written to in output.F, in code like:

Code: Select all

              WRITE (HIS(ng)%name,10) TRIM(HIS(ng)%base), ifile
#ifdef LONG_NUMS
  10          FORMAT (a,'_',i5.5,'.nc')
#else
  10          FORMAT (a,'_',i4.4,'.nc')
#endif
            END IF

where:

Code: Select all

           ifile=(iic(ng)-1)/ndefHIS(ng)+1

What you have done is overflow the integers that fit within four characters. You can do this by having a DSTART such that your first file wants to be number 560924 or by having over 9999 output files. I ran into the latter problem in some applications and added the LONG_NUM option.

Thanks Kate, that has sorted the problem!
