CAM5 with idealized physics

[pkelly]

Is it possible to build and run idealized physics in CAM5 with the CESM1 scripts?
(I undestand this feature was not supported in earlier releases)

Thanks.

No, this isn't supported from the CESM scripts. You need to run CAM using standalone scripts.

Thanks for you response Eaton.

I was able to get CAM running by following the example stand-alone script included with the distribution.

My next question is how to implement code changes using these standalone scripts.

For instance, with CCSM scripts, I put MYMODS.F90 into $CASE/SourceMods/src.cam/
I tried putting MYMODS.F90 directly into .../models/atm/cam/src/ directory before configuring etc.., but this do not work.

Do I have to include a option or flag somewhere in the configure or build command? Again, I am working off the included example (run-ibm.csh) and using these scripts are still quite new to me.

Thanks for any clues!

To specify the directory that contains source mods for CAM you use the -usr_src option to the configure command. Here is a link to the User's Guide where this is documented.
