[Mesa-users] Evolution from main sequence to sub-giant phase

[Francis Timmes]

ok. you will probably be able to answer your own questions if you 

a) go through the "getting started" material that is available 
in prose form 

http://mesa.sourceforge.net/starting.html

or video form

https://youtu.be/b0bZ9FAgyrg

b) carefully explore the defaults

http://mesa.sourceforge.net/star_job_defaults.html
http://mesa.sourceforge.net/controls_defaults.html

but to answer your two questions directly, no and no.
