[gmx-users] Re: crazy temperatures

[Tsjerk Wassenaar]

Hey,

Hotter than the sun only goes for the surface. The core and the corona
are much hotter. Whether electrons get separated from nuclei or
nuclear fusion should start to occur also depends on pressure... But
the question itself pertains to the code and the application of
Newton's equations of motion for particle based systems at very high
temperatures. And there's nothing that should prohibit that. There are
practical issues, of course. The state of the matter you intend to
simulate, the force field, and the time step, definitely.

Cheers,

Tsjerk
