[Mesa-users] A query regarding re-running mesa binary from intermediate steps

Hi Pulkit,

This does sound like a problem, but it's not immediately obvious what the source of the issue is. Could you share some more details to help us diagnose the issue? E.g. a minimal binary work directory setup that reproduces the issue, and some plots that show what ends up being different about the evolution.

If I do it repeatedly for 30 steps (stopping and restarting at every step), then the calculated binary parameters turn out to be different as compared to the case when MESA has run without stopping at intermediate steps.
