What can and cannot be changed post-build


New Member
I am used to making changes to user_nl_xxxx after a CIME case has been built, which as far as I know, is fine since namelists are always generated at runtime.

Can I also do this with env_*xml variables, via xmlchange? Or does xmlchange need to be used only pre-build?

All I am trying to do is change NTASKS.

You can change anything in env_run.xml at any time. The other xml files are all pre-build. If you wish to change NTASKS, you will need to do:

./case.setup --reset

./case.build --clean-all
