Block-Structured Solution of Three-Dimensional Transonic Flows Using Parallel Processing

Abstract

The main objective of the program has been to implement and test the three-dimensional. block-structured Euler solver on computers with multiple processors. The developed scheme involves the partitioning of a large aerodynamics problem into several smaller problems where each represents a particular flow region. Each of these problems are Intel-IPSC computer with sixteen processors and IBM 3090 computer with four processors. In the case of IPSC, the memory is distributed between sixteen processors (4.5 megabytes each). In the case of IBM 3090, all four processors share the same large memory. Several test cases have been run on these computers and basic considerations for analyzing large problems on parallel computers have been investigated. Keywords: Transonic flows; Zonal methods; Euler equations; Parallel processing.
