Journal ArticleDOI
Direct simulation Monte Carlo on petaflop supercomputers and beyond
Steven J. Plimpton,Stan Gerald Moore,Arnaud Borner,A. K. Stagg,Timothy P. Koehler,John R. Torczynski,Michail A. Gallis +6 more
TL;DR: SPARTA as mentioned in this paper is an implementation of the Direct Simulation Monte Carlo (DSMC) method for modeling rarefied gas dynamics in a variety of scenarios, and it can operate in parallel at the scale of many billions of particles or grid cells.
Proceedings ArticleDOI
Direct simulation Monte Carlo: The quest for speed
Michail A. Gallis,John Robert Torczynski,Steven J. Plimpton,Daniel J. Rader,Timothy P. Koehler +4 more
TL;DR: In the 50 years since its invention, the acceptance and applicability of the DSMC method have increased significantly, whereas the increase in computer speed has been the main factor behind its greater applicability.
Journal ArticleDOI
Accuracy and efficiency of the sophisticated direct simulation Monte Carlo algorithm for simulating noncontinuum gas flows
TL;DR: In this article, the accuracy of a recently proposed direct simulation Monte Carlo (DSMC) algorithm, termed "sophisticated DSMC", is investigated by comparing simulation results to analytical solutions of the Boltzmann equation for one-dimensional Fourier Couette flow.
Journal ArticleDOI
Convergence behavior of a new DSMC algorithm
TL;DR: The new algorithm is shown to significantly reduce the computational resources required for a DSMC simulation to achieve a particular level of accuracy, thus improving the efficiency of the method by a factor of 2.5.
Journal ArticleDOI
An approach for simulating the transport of spherical particles in a rarefied gas flow via the direct simulation Monte Carlo method
TL;DR: In this paper, an approach for computing the force on and heat transfer to a spherical particle from a rarefied flow of a monatomic gas that is computed using the direct simulation Monte Carlo (DSMC) method is presented.
