[Mesa-users] other_torque subroutine computed twice

[Pablo Marchant]

Hi Miriam,

this behavior is normal. Angular momentum transport is split from the
general newton solver for the rest of the structure equations. By default,
it is split such that mixing is computed for dt/2 before the newton solver,
and dt/2 after the newton solver. This is the reason why you see two calls
each step. Being more specific, this behavior is controlled by the option
premix_omega, which is true by default.

Cheers
