[mesa-users] v_flag

[Yevgeni Kissin]

Dear MESA community,

I am currently working on massive star evolution and am basing my model on
the 'inlist_massive_defaults' file, in
version 7503. There are plenty of flags explicitly included in this inlist,
some of which are simply set to the default.
But ignoring these, I am attempting to reduce the flags set to non-default
values, by understanding what each
represents.

v_flag is one that I am confused about. I do not understand what it does,
nor can I find an explanation of it in either
the star_job.defaults, or this mailing list. Can anybody provide me with a
physical explanation as to what it does?

And while I have your (collective) brains to pick, I am also surprised at
the choice of overshoot parameters in this
inlist. Specifically, the choice of 0.001 for non_burn and h which is below
the recommended value in the MESA
paper on massive stars, and 0 for he and z.

Thank you very much,
