[Mesa-users] Terminated evolution of F type star

[Jared Goldberg]

Hi Kira,

This is the standard "the code crashed" error. The next step is figuring
out what is setting your timestep and what is causing the crashes.
There are lots of suggestions for debugging here:
https://docs.mesastar.org/en/latest/developing/debugging.html

If it's a hydro problem, there's good info (albeit somewhat out of date
with MESA revisions) here: https://billwolf.space/projects/mesa_debugging/

We also tend to ask for more information to help debug:
https://docs.mesastar.org/en/latest/installation.html#post-a-question-to-mesa-users

The more information you can give us to describe the problem, and the more
output you give the better. What's setting the timesteps? What happens in
the star to cause the crash? Does something go haywire in any of your
pgstar output? Etc. The timestep is adaptive, so when it plummets below the
limit, that tends to indicate that something else is going wrong, a
residual is too large, and the code attempts to take a smaller timestep in
order to get the residuals under control.

Best,
~Jared
