The RRM branch has been merged to the ACME master.  Please see the updated 'how-to' document:   How to run the regionally refined model (RRM)

Please follow the steps below when wanting to run When creating the regionally refined model (RRM) CONUS grid in ACMEcase, please refer to the steps in this article.

1. Checkout the tangq/cam/RRM branch - see Development Quick StartGuide for details

1. .
2. Create and build a new case from the scripts directory

1. Suggested syntax:
   1. $ ./create_newcase -res conusx4v1_conusx4v1 -case $CASENAME -compset
   FC5 -mach (your-machine-name-here) -res conusx4v1_conusx4v1
   1. $COMPSET -mach $MACH -project $PROJECT
2. Edit env_mach_pes.xml as needed.  For Sandia's Redsky machine, using 200 cores and 1 thread for each component runs at 0.25 simulated years per day.
3. Edit env_run.xml as needed to specify the run-length. 
   1. set EPS_AAREA equal to 9.0e-06
      (or else you might see the error: "incompatible domain grid coordinate")
4. Set-up and build the case.
   $ ./cesm_setup   
   $ ./$CASENAME.build  
    (When building a case for the first time, the script will look for the boundary and initial condition files which are located on the ACME data server.  See /wiki/spaces/WORKFLOW/pages/7998629 ACME Input Data Repository.)
5. Edit the namelist files (i.e., user_nl_cam) for user-specified output settings. 
6. Run your $CASENAME!
