Determining interaction rules in animal swarms
Anders Eriksson, Martin Nilsson Jacobi, Johan Nystrom +1
In this paper we introduce a method for determining local interaction rules in animal swarms. The method is based on the assumption that the behavior of individuals in a swarm can…
On the microscopic foundation of dissipative particle dynamics
Anders Eriksson, Martin Nilsson Jacobi, Johan Nystrom +1
Mesoscopic particle based fluid models, such as dissipative particle dynamics, are usually assumed to be coarse-grained representations of an underlying microscopic fluid. A fundam…
Bottom-up derivation of an effective thermostat for united atoms simulations of water
Anders Eriksson, Martin Nilsson Jacobi, Johan Nystrom +1
In this article we derive the effective pairwise interactions in a Langevin type united atoms model of water. The interactions are determined from the trajectories of a detailed mo…
Using force covariance to derive effective stochastic interactions in dissipative particle dynamics
Anders Eriksson, Martin Nilsson Jacobi, Johan Nyström +1
There exist methods for determining effective conservative interactions in coarse grained particle based mesoscopic simulations. The resulting models can be used to capture thermal…
