[Mesa-users] Giving MESA parameters from the command line

[Adam Jermyn]

Hi Jeremy,

You can write a wrapper script to start up MESA runs with specific parameters. I usually make a ‘prototype’ MESA directory with inlists containing the parameters I’ll be changing. In the prototype directory I  set those to some placeholder like <<MASS>>. At runtime I copy the prototype directory and then use sed to replace each placeholder with the value I want.

If you want to get output directly from MESA without going through the history/profile files you can always add write statements to your run_star_extras.f. When I do this I usually add an identifiable string before the output so that I can easily search for the lines I need.

Hope this helps,

-Adam
