[mesa-users] How to make mesa write output at specific ages?

[Earl Bellinger]

Hi Pritesh,

The MESA controls inlist has the option

    max_age

which you can set, for example, to the age of the sun:

    max_age = 4.57e9

If you want to output multiple ages, you can write a bash script that will
run the script until the desired age, then sed out that age and put in the
new one, run until the next desired age, etc. It might look something like:

mk
rn
sed -i.bak "s/\max_age = 4.57e9/max_age = 13.8e9/g" inlist_1.0
rn

which will run until the age of the sun, then change the max age to the age
of the universe, and then rerun until then.

There are also controls for the timestepping, for example you can change
max_years_for_timestep.

Good luck!
