running CLM4.5 in CESM1.2

[mvparke@sandia_gov]

I am using CESM1.2 (rel 06) and trying to run a simulation using CLM4.5, to examine the methane released from the land model. I can't output methane history variables in CLM4.0, so want to try CLM4.5. Eventually I'd like to run a simulation with the CLM4ME model, which is only available in CLM4.5. I am most interested in the atmosphere, so have been running F compsets such as FMOZMAM (2000_CAM5%MOZM_CLM40%CN_CICE%PRES_DOCN%DOM_RTM_SGLC_SWAV). When I try to use CLM45 instead of CLM40, the simulation fails to build (error "set_compset: exiting"). I've tried the following:1. using the FMOZMAM compset, then changing CLM_CONFIG_OPTS to "-phys clm4_5 -bgc cn" in env_build.xml2. running with a compset that should use CLM4.5 (B1850CLM45CN, FC5L45BGC, F1850PDC5L45BGC, and F1850C5L45BGC)3. Specifying my own compset in long form (2000_CAM5%MOZM_CLM45%CN_CICE%PRES_DOCN%DOM_RTM_SGLC_SWAV) Has anyone else run into this problem, or have any suggestions on how I might be able to use CLM4.5? I'd really appreciate any suggestions! Thanks in advance,Marie

I'm not sure why you are getting that specific error, but I tried the following with cesm1_2_2 which seemed to work (it built at least, but I didn't try to run it):./create_newcase -case CESM1_2_2_FMOZMAM -res f09_g16 -compset FMOZMAM -mach yellowstonechanged CLM_CONFIG_OPTS to "-phys clm4_5 -bgc cn" in env_build.xml./cesm_setup./CESM1_2_2_FMOZMAM.buildHope this helps.
