Iterative boltzmann inversion method

WebWe use Iterative Boltzmann Inversion to discover pair potentials that yield cluster uids. To do this we need a target radial distribution function, which we sample from a system with a many-body potential that was designed to yield cluster uids. Prearranged clusters do tend to stay together with the potentials we nd, but when Web25 mei 2024 · Then, a coarse-grained model of PUU was successfully constructed using the iteration Boltzmann inversion (IBI) method. Microphase separation and mechanical properties of PUU were reproduced using this model by coarse-grained molecular dynamics (MD) simulation. The three-stage healing mechanism comprised the following: (1) ...

Web9 jan. 2014 · In this work, we propose an in situ parameterisation method with reduced transferability but maximal accuracy for the chemical and physical environment under investigation. Starting from an initial guess, we used iterative Boltzmann inversion to successively improve the repulsive potentials. WebIn this work, an extension is proposed to the standard iterative Boltzmann inversion (IBI) method used to derive coarse-grained potentials. It is shown that the inclusion of target data from multiple states yields a less state-dependent potential, and is thus better suited to simulate systems over a range of thermodynamic states than the standard IBI method.
