[mesa-users] Massive binary evolution

[Pablo Marchant]

Manos, in case you have systems that evolve into contact, and you want to
proceed further, you can use the control:

factor_for_contact_terminate = 1.0d0

just put this into the &binary_controls section of your inlist_project.
This gives the value of R/R_l at which evolution will terminate. If you
want to keep going just increase that number, but be warned, nothing is
being done to take into account that the stars are in contact.

Cheers!
