Entropy Conservation

Dear Gdget list,

In the file timestep.c, we can find the explicit comment (followed by
the corresponding instructions) :

           /* In case of cooling, we prevent that the entropy (and
             hence temperature decreases by more than a factor 0.5 */

I was asking me if it was not better to add a constraint on dt (in
get_timestep)
that ensure for example that the variation of the entropy due to the
cooling is
less than for example 10% of its value.

Thanks for giving me your opignon.

Cheers.
