شبیه سازی پدیده تجمع پلاکت خون به روش dissipative particle dynamics

موازی سازی شبیه سازی پدیده ناپایداری دوجریانی به روش PIC

Two stream instability in plasma is simulated by PIC method. The execution time of the sequential and parallizable sections of the program is measured. The sequential program is parallelized with the help of the MPI functions. Then, the execution time of the sequential program versus the number of the grid points and the execution time of the parallel program on 3 and 5 processors versus the nu...

Anisotropic single-particle dissipative particle dynamics model

D Dissipative Particle Dynamics , Overview

Natural systems can be described at different scales based on both spatial and temporal size. In general, there are three different scales, i.e., micro-, meso-, and macroscales. A microscopic event occurs at nanometers in length and nanoseconds in time or, even less, governed by quantum mechanics or classical laws. Macroscale describes physical objects or phenomena that are measurable and visib...

Splitting for Dissipative Particle Dynamics

We study numerical methods for dissipative particle dynamics, a system of stochastic differential equations for simulating particles interacting pairwise according to a soft potential at constant temperature where the total momentum is conserved. We introduce splitting methods and examine the behavior of these methods experimentally. The performance of the methods, particularly temperature cont...

A splitting scheme for highly dissipative Smoothed Dissipative Particle Dynamics

Smoothed Dissipative Particle Dynamics (SDPD) is a novel coarse-grained mesoscopic method for the simulation of complex fluids representing the effect of microscopic scales by a stochastic process. It has some advantages over more traditional particle-based methods but, on the other hand, shares some problems common to particle-based simulations of microfluidic systems. In particular a prohibit...
