question about dynamic global vegetaition

[MikeYuan]

Hello, I chose the compset IHistClm50BgcCrop to simulate the dynamic global vegetaition, but I have no idea how to turn on it, should I set the "use_cndv"?
But I could't found this namelist variable in my lnd_in file.
The doubt made me confused.

The DGVM is not supported in recent versions of the model nor is it likely to work well or at all.

Thanks for your reply, Mr.Oleson
But I am using the version of CESM2.1.2, doesn't it still work?

You would have to go back to the CESM1 series to get a version that would run properly in a scientifically supported configuration.

You can try turning it on by setting use_cndv = .true. in your user_nl_clm. But I doubt it will work well or at all, and we don't support it anymore.

Thanks for your suggestion, Mr.Oleson. But it showed the following error:
err=ERROR : CLM build-namelist::CLMBuildNamelist::setup_cmdl_dynamic_vegetation() : use_cndv is inconsistent with the commandline setting of -dynamic_vegetation

You need to turn it on using the CLM_BLDNML_OPT xml variable. So you add "-dynamic_vegetation" to the end of that XML variable. You can use ./xmlchange --append to do that, or edit the xml file directly.
