[Mesa-users] Change_E_flag

[Subedi, Shiv Kumar]

Hello Frank,

Thank you for your suggestion. I commented out the "Change_E_flag" and "new_E_flag" and it solved the problem.
However now I have error message for one of the controls variables.
Fortran runtime error: Cannot match namelist object name use_hydrodynamic_surface_bcs

The controls.defaults section of mesa-r7624 prpvides following description of the variable.

!### use_hydrodynamic_surface_BCs

         ! 1) gradient of compression vanishes at surface
            ! see Grott, Chernigovski, Glatzel, 2005.
            ! d_dm(d_dm(r^2*v)) = 0 at surface
            ! by continuity, this is d_dm(d_dt(1/rho)) = 0 at surface
            ! finite volume form is
            ! (1/rho(1) - 1/rho_start(1)) = (1/rho(2) - 1/rho_start(2))
            ! this BC determines the density for surface cell.

         ! 2) black body radiation at surface
            ! L = 4*pi*R^2*boltz_sig*T^4
            ! this BC determines the temperature for the surface cell given R and L.

      use_hydrodynamic_surface_BCs = .false.

However controls.defaults in mesa-r10108 doesnot have any description of the above variable.
I am not sure if I should comment out every variable from the old inlist which have no description in the defaults section of new mesa version.

Could you please provide your suggestions about the problem?

Best,
Shiv Subedi

hi shiv,

perhaps just remove the old change_E_flag from the inlist.
