[Mesa-users] Dh_div_H_limit

[Hannah Brinkman]

Dear All,

When checking some of my recent models, I see a lot of times that the
timestep is limited by DH/H. After checking this in the controls, I noticed
that when this limiter appears, the timestep is decreased by
DH_limit/max_DH. However, DH_limit is 1d99 by default. Wouldn't this lead
to an enormous decrease of the timestep each time this control limits the
timestep? Or do I misinterpret this limiter? I cannot find what determines
max_dH.

I hope someone can explain to me what is happening in the star when this
limiter shows up.

With kind regards,
Hannah
