[Mesa-users] resolution issues

[Francis Timmes]

i applaud your testing of convergence in mesa models.
with var_control this is a temporal convergence study,
which is distinct from but related to a mass/spatial 
resolution exploration.

i'm unsure what is meant here on several fronts. do the differences 
refer to the evolutionary age or radius in your plots? why are the 
differences considered "drastic"? mixing of chemical elements, 
in a broad sense, is always on. does "mixing" refer to the 
D_omega_flag, convective_bdy_weight or something else in the inlist?

I seem to be getting sizeable difference in the time it takes to reach the end of main sequence when I turn up the resolution on this control. I have ran this control at 1d-3, 1d-4, and 5d-5 and have notice that I only get such a drastic difference when I have mixing on.

I have provided some graphs of the data I collected, one with mixing on and winds on and one without, and the inlist I am using for these parameters on the later is the same just with these controls commented out.
