[Mesa-users] Mass relax for a binary

[Rob Farmer]

Hi,
Well it should only go in inlist1 or inlist2 star_jiob section (as those
control the stars) not inlist_project (which controls the binary), hence
the error message "Fortran runtime error: Cannot match namelist object name
relax_mass" which is clearly telling you it's in the wrong namelist.

 !relax_mass = .true.
   !new_mass = 1.0

I assume you are uncommetning these options?

 relax_mass = .true.
  new_mass = 1.0

Otherwise they would have no effect.

Rob
