Hello,

I tried to create a new case for CESM 2.2 (Cam-Chem - MUSICA V0 https://wiki.ucar.edu/display/MUSICA/MUSICA+version+0 ). When I run create_newcase, the script could not find the machine file:

python --version
Python 3.8.3

(base) [sibarra@baal scripts]$ ./create_newcase --compset FCnudged --res ne0CONUSne30x8_ne0CONUSne30x8_mt12 --case /p1-baal/sibarra/teste1

So the machine match is determined by a regular expression field in the config_machines.xml file, that field
is NODENAME_REGEX and it should match the string baal.varal.iag.usp.br. I suspect something like
<NODENAME_REGEX>*.iag.usp.br</NODENAME_REGEX> might work. You can also avoid this message by identifying the machine on the command line with the argument --machine $MACH where $MACH is the field in <machine MACH="whatyoucallit">
