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. Tīmeklis2024. gada 12. maijs · Dears I have a problem about using Buckingham potential.
