Web2 jun. 2016 · A coarse-grained water model is developed using multistate iterative Boltzmann inversion. Following previous work, the k-means algorithm is used to dynamically map multiple water molecules to a single coarse-grained bead, allowing the use of structure-based coarse-graining methods.The model is derived to match the bulk and … WebBoltzmann inversion. In structure matching methods, potentials between the CG sites are determined by fitting structural properties, typically radial distribution functions (RDF), obtained from MD employing the CG potential (CG-MD), to those of the original atomistic system. This is often achieved by either of two closely related methods ...
WebAbstract: We demonstrate how an iterative method for potential inversion from distribution functions developed for simple liquid systems can be generalized to polymer systems. It … 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
Web29 sep. 2024 · The iterative Boltzmann inversion is an iterative scheme to determine an effective pair potential for an ensemble of identical particles in thermal equilibrium from the corresponding radial distribution function. Although the method is reported to work reasonably well in practice, it still lacks a rigorous convergence analysis.
