Dear LAMMPS Users,
I am stuck with a problem with the variable getenv arg command and I would appreciate very much any suggestions.
I have been trying to import an environment variable to LAMMPS as a variable to be used for a directory name to save the results. However, despite the fact that I get no error from the process, the variable remains empty instead of having the appropriate string.
My code is:
shell . ./script.sh (Creates folders and exports parent directory name to shell as $PMF - validated!)
variable test getenv PMF ( Doesn’t seem to work with neither PMF, {PMF}, %PMF, 'PMF' etc.) *print "{test} "* (In the end, it doesn’t plot anything, although the script ends correctly)
I don’t understand why it cannot import it. I suspect that the problem is in the syntax but I couldn’t find any relevant example with getenv. Do you have any ideas?
Thank you in advance,
