[Mesa-users] WARNING: rel_run_E_err

[Aaron Dotter]

Hi Jelena,

This is a warning message that was added between 10398 and the version
released with the MESA V paper (Paxton et al. 2019, see section 3).

         ! rel_run_E_err = abs(cumulative_energy_error/total_energy)
         ! you can turn off this warning message by setting this to a large
number.

      warn_when_large_rel_run_E_err = 0.02d0

It's an estimate of numerical energy conservation.  You can make it go away
by setting the above control to a large value.
