Energy-momentum conserving integration schemes for molecular dynamics

نویسندگان

چکیده

We address the formulation and analysis of energy momentum conserving time integration schemes in context particle dynamics, particular atomic systems. The article identifies three critical aspects these models that demand a careful when discretized: first, treatment periodic boundary conditions; second, approximations systems with three-body interaction forces; third, their extension to functional potentials. These issues, interplay Energy-Momentum integrators, are studied detail. Novel expressions for proposed numerical examples given illustrate performance.

Objective energy–momentum conserving integration for the constrained dynamics of geometrically exact beams

In this paper the results in [S. Leyendecker, P. Betsch, P. Steinmann, Energy-conserving integration of constrained Hamiltonian systems—a comparison of approaches, Comput. Mech. 33 (2004) 174–185] are extended to geometrically exact beams. The finite element formulation for nonlinear beams in terms of directors, providing a framework for the objective description of their dynamics, is considere...

Conserving energy and momentum in nonlinear dynamics: A simple implicit time integration scheme

We focus on a simple implicit time integration scheme for the transient response solution of structures when large deformations and long time durations are considered. Our aim is to have a practical method of implicit time integration for analyses in which the widely used Newmark time integration procedure is not conserving energy and momentum, and is unstable. The method of time integration di...

Energy-conserving, Linear-scaling Quantum Molecular Dynamics

Marc J. Cawkwell, Anders M. N. Niklasson, T-1 Molecular dynamics (MD) simulations are used heavily in materials science, chemistry, and biology to study the evolution of structures, defects, and non-equilibrium phenomena at the atomic scale. In an MD simulation atoms move over a number of finite time steps according to the force acting on them. These forces are computed from the interatomic pot...

Explicit Momentum Conserving Algorithms for Rigid Body Dynamics

Two new explicit time integration algorithms are presented for solving the equations of motion of rigid body dynamics that identically preserve angular momentum in the absence of applied torques. This is achieved by expressing the equations of motion in conservation form. Both algorithms also eliminate the need for computing the angular acceleration. The first algorithm employs a one-pass predi...

Momentum conserving Brownian dynamics propagator for complex soft matter fluids.

We present a Galilean invariant, momentum conserving first order Brownian dynamics scheme for coarse-grained simulations of highly frictional soft matter systems. Friction forces are taken to be with respect to moving background material. The motion of the background material is described by locally averaged velocities in the neighborhood of the dissolved coarse coordinates. The velocity variab...
