Procedure for Adapting Direct Simulation Monte Carlo Meshes

摘要

A technique is presented for adapting computational meshes used in the G2 versionof the direct simulation Monte Carlo method. The physical ideas underlying the technique are discussed, and adaptation formulas are developed for use on solutions generated from an initial mesh. The effect of statistical scatter on adaptation is addressed, and results demonstrate the ability of this technique to achieve more accurate results without increasing necessary computational resources.
