Configure history output interval smaller than an hour

Is it possible to set the output interval to every 15 or 30 minutes? Following the User's Guide page, in the model_configure file, I set "output_fh=0.25 -1" that allows real numbers and saw that this can overwrite the integer-only nfhout=1. However, the output frequency is still once/hour. 

Thanks in advance for your help!

Hi,

Thanks for testing and reporting the issue. It looks to me that we still miss some code changes to set up correct time stamp in the file name. Some simple change is listed below to output all the history files

-      if (nsout > 0) then

+      if (nsout > 0 .or. nf_minutes > 0 .or. nseconds > 0) then

However there are still other issues such as the post process filenames if you are running inline post, that requires upp library change. An issue was created in ufs-weather-model repo at https://github.com/ufs-community/ufs-weather-model/issues/826 to completely fix the issue. Please let us know if you have further questions, thanks. 

Also, please note that model can only output history files at forecast hours=multiple of time steps, e.g. if you have time step 720s, you won't have outputs at fh=0.25h=900s
