[Mesa-users] Failed to open start.mod error

[Rob Farmer]

Hi,
Please do not send zip folders with your LOG folders in. We do not need to
see all the data you have generated, only the inlists you use.

starts running.

You should follow the path for how MESA runs a model.

First look in your ./rn file, there you find:

./star

This means MESA is running in its default mode, which is to look for a file
called "inlist". If you look at the inlist file you'll see that it only
loads inlist_3M_prems_to_AGB which is the file that looks for the start.mod
file. start.mod is however only made in inlist_start so you need to run
that inlist instead.

To run your inlist_start_header you must tell MESA to run that inlist, this
means in your ./rn script you can do:

cp inlist_start_header inlist
./star
cp inlist_3M_prems_to_agb_header inlist
./star

To copy the header inlists to the file "inlist" then run that inlist, then
move to the next inlist.
