[Mesa-users] Problem with 1 solar mass stars

Hi Alejandro,

You have the lines:

  ! stop when the center mass fraction of h1 drops below this limit
    xa_central_lower_limit_species(1) = 'h1'
    xa_central_lower_limit(1) = 1d-3

in your inlist_project.  That's why the 1Msun model is stopping at model
number 444.  If you want it to stop at another location, you can change the
stopping condition(s).

As to the video, maybe you have some old files in the directory where you
store the graphical output?  Try removing all files from that directory
before you make a new movie.
