[mesa-users] Overflowing initial model for binary systems

Hi everyone,

I've been using MESA to investigate population II and III stars by
controlling this intial_z value for singular stars. This was working fine
until I moved to the binary case, where I used the second set of
instructions from this
<https://sourceforge.net/p/mesa/mailman/message/34896105/> post to create
my own ZAMS model with certain initial_z values, then matching that in the
inlists from the binary work folder.

I've been having problems trying to evolve the system, even if I set
evolve_both_stars to false (after initially trying true). The first
termination code read "Terminate because of overflowing initial model", so
I tried increasing the initial period as some users had suggested, and
later tried setting ignore_rlof to true, both of which resulted in failure
to find a suitable model. I'm not really sure where to go from here, so
I've attached my inlists (the only ones I edited) and the
inlist_zams_specification I used. I'd greatly appreciate any help with this.

Thanks!
