[mesa-users] Timestep control

[Mathieu]

Hi everyone,

I have a (probably silly) doubt on the timestep control MESA does by 
default.
If I am correct, in the two-stage process of picking the new timestep 
there isn't any explicit comparison between the timestep, the thermal 
timescale, mass loss timescale and other relevant time scales? So 
nothing forces the timestep to be smaller than, say, the thermal timescale?
Or is the comparison implicitly done by the digital control-based scheme 
(I am still a bit confused by this)?

Thanks,

Mathieu
