[mesa-users] New approx21 in MESA

[Manos Chatzopoulos]

Dear all,

  In the last release it was indicated that:

"re implement approx21 for better performance and numerical stability 
using Frank's code as basis.
introduce quad precision calculation of dydt"

  So, in principle just calling the star_job option

new_net_name = 'approx21.net'

  Will automatically allow the newly implemented and improved version of 
the approx21 network to run right? Nothing
else special flag options need to be turned on?

  Is that supposed to enhance numerical performance toward the very late 
stages of stellar evolution (past core Si/S burning?)

Thanks,

Manos
