[Mesa-users] Double Roche lobe overflow

[Pablo Marchant]

Also, there is an implementation of a simple contact prescription I
developed, which is explained in

http://adsabs.harvard.edu/cgi-bin/nph-data_query?bibcode=2016A%26A...588A..50M&db_key=AST&link_type=ABSTRACT&high=51ac7f347015896

you can use this by setting mdot_scheme = "contact" in your inlist_project.
Not quite what you say, but I think under certain conditions its a more
physically correct choice.

Cheers
