frames_per_wrfbdy file limit, NDOWN.EXE

Hi

I am running ndown.exe to get the BCs from domain 01 to domain 02, for a 12 hour period, for every second. I have wrfout_d01 files for every hour with 3600 frames in them for every second. I would like to create wrfbdy_d02 for the whole 12 hour period. I have been running ndown successfully without any errors. It goes smoothly over the whole 12 hour period. However, when I check the wrfbdy_d02 it only contains the first 10000 seconds. I started ndown again from 3 hours later, however, again wrfbdy_d02 only contains the first 10000 time steps. Is there any way I can increase this limit? is this hardcoded or is there any variable that I need to set up in my namelist?

Thanks,
Mahdad

Hi Mahdad,

Take a look in the file WRF/external/io_netcdf/wrf_io.F90. Near the top of the file, you should see:
integer parameter :: MaxTimes = 10000

You can increase that value, and then you'll need to recompile the code to incorporate the change. This should allow you to have more frames in your files.

Hi Kelly,

Thank you so much for your quick response.
