Witryna1 maj 2024 · Already in the 1990s, Voter proposed the hyperdynamics method to accelerate MD simulation of infrequent events in solids [6]. The basic idea of hyperdynamics is to push the system out of the energetic local minima, i.e. the potential energy basin, by adding additional bias to the potential energy surface. http://li.mit.edu/Archive/Papers/10/Hara10.pdf

Witryna28 gru 2024 · The diffusion of a vacancy in a deformed aluminum crystal is simulated by the methods of hyperdynamics and classical molecular dynamics. The method used to construct the bias potential for the hyperdynamic method was previously developed for the example of two-dimensional systems using pair potentials. The results indicate the … WitrynaThis command can be used to run both global and local hyperdynamics. In global HD a single bond within the system is biased on each timestep. In local HD multiple bonds (separated by a sufficient distance) can be biased simultaneously at each timestep. In the bond-boost hyperdynamics context, a “bond” is not a covalent bond between a pair ...
