[mesa-users] MESA Config files, question about inlist and running my own simulation

tuned to each specific test_suite evolution?

So most of MESA configuration is done in the inlists, but you would also
need to copy over the src/run_star_extras.f file to make sure you had the
same run. There can also be a slight complication with information coming
from a saved model if loading a mod file up or a photo if doing a restart
as well. And to get the same output you would need to copy over the
history_columns and profile_columns files, if the folder contains them.

"high_mass" folder, it would in fact be incorrect?

That would evolve a 1 solar mass star, but it might not look like a 1 solar
mass star from the 1M_pre_ms_to_wd folder depending on differences in other
parameters set in the inlists.
