[Mesa-users] How to adjust gradr and get surface cell density though other_mlt.f90

It is a great method to change gradr and I have done it in run_star_extras.

I believe that gradr_factor does affect d_gradr_dvb.  It does not appear
explicitly because of the redefinition as gradr=gradr*gradr_factor .


Besides, the new gardr_factor contains the adiabatic  gradient, whether it

I did not understand this part of your message.
