[mesa-users] setting Atmosphere

[Robert Farmer]

Hi
>sufficient to have MESA models with atmosphere Included.

All models have an atmosphere, as we need something for the outer boundary
condition, I would suggest just deleting that option and letting mesa use
its defaults unless you have good reason to want to change it. Or you could
experiment and see what happens when you change that value?

>How do I set mesh point at the center (r = 0)?
We don't have points directly at 0, but there is one close to zero

max_center_cell_dq = 1d-7
http://mesa.sourceforge.net/controls_defaults.html#mesh_adjustment

Sets the maximum mass (in mass ratio units) of the central cell. Why do you
need a point directly at r=0?
