[Mesa-users] Time step error

[Wampler, Steven]

Hi Frank/everyone,

*Here's a little more information about what I'm doing. I'm using the
inlists and run_star_extras* downloaded from the Marchant paper repository
on PPISN and using the current revision of MESA. The paper used r11123 ( I
think). We expected to run sim on a 46 M_sun star and have it go through
several pulsations then reach core-collapse. However after the first pulse
the time step tanks and I'm not sure why or what steps to take to try and
fix it.

Thanks,
Cole Wampler
