Parallel Approach of Fully Systemized Chimera Methodology for Steady/Unsteady Problems

The development of a parallelized aerodynamic simulation process involving moving bodies is presented. The implementation of this process is demonstrated using a fully systemized Chimera methodology for steady and unsteady problems. This methodology consists of a Chimera hole-cutting, a new cut-paste algorithm for optimal mesh interface generation and a two-step search method for donor cell identification. It is fully automated and requires minimal user input. All procedures of the Chimera technique are parallelized using the MPI library. In the case of a test, two and three-dimensional problems are simulated on Cray T3E.
