TīmeklisLAMMPS Buckingham potential for a-Al2O3 developed by Sun et al. (2006) v000; This is only the a-Al2O3 interactions of a simple transferable rigid-ion potential for binary, highly ionic oxides. The van der Waals terms involving cations and the cation–cation short-range repulsive interactions do not appear explicitly. The potential parameters … TīmeklisSets of self-consistent oxygen-rare earth (RE = La, Y, Lu, Sc) interatomic potential parameters are derived using a force-matching procedure and utilized in molecular dynamics (MD) simulations...

TīmeklisIn order to show how the potential model can be used in LAMMPS a working example has been provided. The LAMMPS_example.zip provides an example where a 4×4×4 UO 2 super-cell is energy minimised then equilibrated under NPT conditions at a temperature of 300K for 50ps.

http://bbs.keinsci.com/thread-36441-1-1.html TīmeklisIssues ¶. This potential has the risk of an un-physical “Buckingham catastrophe” which is where in charged systems the electrostatic attracion can overcome the repulsive barrier and lead atoms being strongly bonded with a distance of 0. This is about 4 times slower then the lennard jones potential to compute. TīmeklisIt has been determined by molecular dynamics simulation method the parameter potentials ( ε, σ ) of the Lennard-Jones potential based on the cohesive energy value for some pure metals.
