Describe every step you took leading up to the problem:
I want to create a new case including the modifications indicated and run it in our local machines

Describe your problem or question:
Once the script starts to create the case shows this on screen:

...
Could not find machine match for 'bn15.cluster.net' or 'bn15.cluster.net'
Could not find machine match for 'bn15.cluster.net' or 'bn15.cluster.net'

IOError: [Errno 2] No such file or directory: '~/CESM2.2/cime/config/e3sm/machines/config_machines.xml'
...

But in the machine, ~/CESM2.2/cime/config/e3sm/machines/config_machines.xml does not exit.
Only can reach up to:

~/CESM2.2/cime/config/e3sm/

where there is only this xml file:

config_files.xml

How can I configure the machines to be used by CESM?.

Thanks in advance
