Equation of motion for coarse-grained simulation based on microscopic description.

چکیده
We have derived an equation of motion for coarse-grained particles by using a projection operator. Because the derived coarse-grained equation is based on microscopic description, it can be the basis for models of various coarse-grained simulations. We show that by substitution of random forces into fluctuating forces in the coarse-grained equation, the equations for Brownian dynamics and dissipative particle dynamics are reproduced.

Coarse-grained computation of traveling waves of lattice Boltzmann models with Newton–Krylov solvers
For many complex dynamical systems, a separation of scales prevails between the (microscopic) level of description of the available model, and the (macroscopic) level at which one would like to observe and analyze the system. For this type of problems, an “equation-free” framework has recently been proposed. Using appropriately initialized microscopic simulations, one can build a coarse-grained...

متن کاملTension dynamics in semiflexible polymers. I. Coarse-grained equations of motion.
Based on the wormlike chain model, a coarse-grained description of the nonlinear dynamics of a weakly bending semiflexible polymer is developed. By means of a multiple-scale perturbation analysis, a length-scale separation inherent to the weakly bending limit is exploited to reveal the deterministic nature of the spatio temporal relaxation of the backbone tension and to deduce the corresponding...
متن کاملMathematical Tools for Error Analysis of Coarse-graining of Lattice Systems
Coupling microscopic simulations with description at larger scales has been one of the principal tasks in many areas of computational modelling. We discuss some general mathematical issues arising in problems where the microscopic Markov process is approximated by a hierarchy of coarse-grained processes. We provide both analytical and numerical evidence that the hierarchy of the coarse models i...
متن کاملAn experimental study on hydraulic behavior of free-surface radial flow in coarse-grained porous media
The equations of fluids in porous media are very useful in designing the rockfill and diversion dams, gabions, breakwaters and ground water reserves. Researches have been showed that the Forchheimer equation is not sufficient for the analysis of hydraulic behavior of free-surface radial flows; because, in these flows, in addition to the hydraulic gradient and velocity, the variable of radius is...
