[mesa-users] HELP. Critical rotation of accretor in binary system

[Pablo Marchant]

Ying, I cant open .fig files (xfig files?), if you send figures please send
them on a more common format (eps, pdf).

Anyhow, what you are trying to do is essentially what is done in section
2.9 of the third mesa paper

http://arxiv.org/abs/1506.03146

all inlists for that paper are available here

http://mesastar.org/results/mesa-iii-instrument-paper-inlists

please start by modyfing those inlists to your particular needs, it will
probably be a more efficient way to get what you want than starting from
scratch.
