how to minimise system using MM in lammps?

hi all,

I read an article which for minimising a system it said that it minimized once using a “NVT” then using “NPT” and then using “MM”. I couldn’t get what “MM” refers to ,and how can I use it in Lammps.

I will be thankful if anybody knows kindly tell it to me.

Regards,

impossible to say without more context. more importantly, "NVT" and
"NPT" are thermodynamic ensembles not minimizers and "MM" usually
stands for molecular mechanics which is a term describing pretty much
any method that uses atomic forces.

if you want to use those in LAMMPS you first of all need to lean
sufficient basic of statistical mechanics and molecular
dynamics/mechanics so that you can make proper sense sense out of what
all these terms mean and more. the LAMMPS documentation assumes that a
user has this kind of knowledge since otherwise you can only do
meaningful work with it by accident.

axel.

MM “should” stand for molecular mechanics. Look into the minimize command for more info.
