Abstract:
An application of the classical molecular dynamics method on supercomputers
is considered. The parallel efficiency of LAMMPS package is studied for up to
8 000 CPUs on MVS-100k installed at JSCC of RAS. Some recommendations for its
efficient usage are proposed. The choice of the number of particles and the
choice of computation time are discussed. A set of molecular dynamics models
and a number of approaches to the simulation of phase transformations and
fracture are given. An analysis of prediction of modeling is carried out on the
basis of the comparison between numerical results and experimental data.
