Application of the Nesvetay Code for Solving Three-Dimensional High-Altitude Aerodynamics Problems

Abstract

A survey of the capabilities of the Nesvetay code as applied to computing the flow of a high-speed monatomic gas around objects of irregular shape for large flight altitudes is given. An implicit numerical method on an arbitrary unstructured grid and a two-level approach to the organization of parallel computations are described. This code is compared with the well-known MONACO and SMILE codes that implement the direct simulation Monte Carlo method.
