[Mesa-users] Adjusting Initial Parameters in make_pre_ccsn_iip

[Francis Timmes]

hi vanessa,

return the ./rn script to its original state.

for continuous integration purposes (i.e., frequent testing) 
certain phases of evolution are skipped to reduce the time it 
takes to test a mesa developers change. in this case, the 
pre-ms stage is skipped, which is why the mass does not change 
even though you change it in inlist_mass_Z_wind_rotation.

if you set the environment variable (assuming a bash shell)

export MESA_RUN_OPTIONAL=1

the original ./rn script will then run all the inlists, 
and thus pick up the mass change in inlist_mass_Z_wind_rotation .

I want to change the star’s initial mass to 30 solar masses. I first went into the inlist_mass_Z_wind_rotation file and under the &controls section changed initial_mass to 30. However, this did not change anything when I actually ran the model, which seemed to be because the rn script starts off with a pre-made model if the string MESA_RUN_OPTIONAL exists somewhere. I could not find where that string appears in order to delete it and force MESA to run the module from the late pre-ZAMS stage, so instead I commented out the if statement in order to only run the “else” portion. My rn script now looks like this:
