[Mesa-users] Differences between MESA versions in Evolution stage

[Aaron Dotter]

Hi,

Your inlists are relying entirely on the MESA defaults.  Changes to the
defaults from one release to another can result in differences for the same
inlist, especially if that inlist leaves most options at their default
values.  I quote from Josiah's reply to James:

"Understanding the option choices (including both options you explicitly
set and key defaults) and their importance in the evolution of the model."

and

"Confirming that the models are converged (i.e., checking that the results
do not significantly depend on the time and spatial resolution)"

These are both salient points to your question.

Aaron
