[mesa-users] Manual refinement in MESA

[Manos Chatzopoulos]

Dear all,

I am a working on a problem with MESA that requires high resolution in a 
specific part of the star (say, the iron core) and lower resolution in 
other parts. Are there any special refinement criteria one can use to 
specify where they need extra refinement (and de-refinement, for that 
matter) or does someone have to manually implement those. You may think 
of this as some form of AMR (Adaptive Mesh Refinement) minus the 
Lagrangian grid of course. More specifically my aim is to run a MESA 
calculation with regular refinement criteria specified by the 
delta_mesh_coeff parameter and then at some point pause and restart with 
more specified refinement for a selected stellar region. Is that 
feasible and is there a way to tackle this?

Thank you very much in advance,

Manos
