(large energies and forces) to still be minimized by pushing the atoms
off of each other.
Alternate means of relaxing a system are to run dynamics with a small
or "limited timestep"_fix_nve_limit.html. Or dynamics can be run
using "fix viscous"_fix_viscous.html to impose a damping force that
slowly drains all kinetic energy from the system. The "pair_style
soft"_pair_soft.html potential can be used to un-overlap atoms while
running dynamics.
Following the minimization a statistical summary is printed that
includes the energy change and convergence criteria information.
@ -98,6 +105,13 @@ external pressure that would be included in the minimization
(i.e. allow the box dimensions to change), but this has not yet been
implemented.
Pair potentials that produce torque on a particle (e.g. "granular
potentials"_pair_gran.html or the "GayBerne
potential"_pair_gayberne.html for ellipsoidal particles) are not
relaxed by a minimization. More specifically, radial relaxations are
induced, but no rotations are induced by a minimization, so such a
system will not fully relax.
