HiMAP: a portable super modular multilevel parallel multidisciplinary process for large scale analysis

An efficient super modular process to simulate aeroelasticity of aerospace vehicles using high fidelity flow equations such as the Euler/Navier-Stokes equations is presented. The process is suitable for both tightly coupled a nd uncoupled analysis. The process is designed to execute on massively para llel processors (MPP) and work-station clusters based on a multiple-instruc tion, multiple-data (MIMD) architecture. The fluids discipline is paralleli zed using a zonal approach whereas the structures discipline is parallelize d using the substructures concept. provision is also made to include contro ls domain. Computations of each discipline are spread across processors usi ng IEEE standard message passing interface (MPI) for inter processor commun ications. Disciplines can run in parallel using a macro utility MPIRUN deve loped based on MPI. In addition to discipline parallelization and coarse-gr ain parallelization of the disciplines, embarrassingly parallel capability to run multiple parameter cases is implemented using a script system. The c ombined effect of three levels of parallelization is an almost linear scala bility for multiple concurrent analyses that pet-form efficiently on MPP. ( C) 2000 Elsevier Science Ltd.
