[Mesa-users] rel_run_E_err warning on simple MS run

[Warrick Ball]

Hi Giovanni,

Try adding this control to &controls:

     use_dedt_form_of_energy_eqn = .true.

You may also want to add:

     use_gold_tolerances = .true.

They've been added to the default `star/work/inlist_project` as of r11701. 
See Section 3 of the new MESA instrument paper for details.

Cheers,
Warrick
