Change history output

You need to do a branch run if you change the history output. You could keep the same name with the variable: 
BRNCH_RETAIN_CASENAME See info at:

From user:

I have run CESM for 6 months without writing out history files to speed up the wall time.  Now, for July, I would like to start writing history files.I edited user_nl_cam to reflect this (using a user_nl_cam file which had worked previously), did a rebuild, and ran for one more month. All indications show that the model did run until 07-30 (restart files, etc).  However, the history files I had specified in user_nl_cam were not there. In an online search, I found that the method I executed is valid for POP and CICE, however, for CCSM4.0, one needs to do a branch run in order to change history file frequency.   Is this still true for CAM5? Thank you ahead for your attention to my question. Best regards,
 
Thank you,Cecile, for your quick reply.I should have specified that I am using CESM1.2.2, and followed instructions on branch runs for that version.The model run does not finish, running for only ~1 minute. The error reported in the cesm.log file is:"(shr_sys_abort) ERROR: (seq_infodata_Check) : invalid continue restart case name = feedback.B1850C5CN.trial2".  There are no typos in the case name listed.Is this referring to the following lines in env_run.xml?           This case does exist, and there is no typo.  The refcase folder is at the same directory hierarchy level as the branch case.Would you have other suggestions as to why I would be getting this error?Thank you,Kuo

I neer had that error but the fact it says: "invalid continue restart" makes me think that your run is not set as a branch run. How do you specify: env_run.xml:  
env_run.xml:  also, please check the variable CONTINUE_RUN :

Do you mean env_conf.xlm rather than env_run.xml? For the latter, the specifications of "GET_REFCASE" and "RUN_REFCASE" does not exist according to the variable list. I'm just wondering because I saw somewhere else also env_run rather than env_conf in a user question and my branch run does not work so far (it did not write out the modified output frequency, just the old one).

Cecile Hannay's response was correct.  She is referring to env_run.xml.  There are specific instructions on how to change the history output files in the middle of a run, in the CESM user guide, actually, and it is very helpful.
