Using a large number of processors, these computations can now be done in a reasonable amount of time. These computer simulations can result in better designs, as well as improved safety margins in submarines undergoing complicated maneuvers. This report treats the performance of the AVBP CFD code on the IBM SP parallel supercomputer with 3D test cases for simple wing geometry and full aircraft geometry. We solve partial differential equations using parallel adaptive finite element methods. Adaptivity allows for greater solution accuracy with a smaller computational cost by concentrating computational effort in parts of the domain where solution resolution is inadequate.
Parallelism allows large-scale problems to be solved.
The solver and dynamic load balancers are built on top of a parallel mesh library developed at Rensselaer. Here, we simulate an Euler flow inside a domain which represents a perforated muzzle brake of a cannon, using an IBM SP computer. Parallel Implementation Of A 2D Aerodynamic Code Terrence Y. Liao, Kambiz Salari, and Patrick J. Roache A serial aerodynamics code is parallelized to run on the massively parallel IBM SP1 and SP2 computers. The serial code uses an implicit, finite volume, approximately factored algorithm which requires operator splitting. In one direction of the operator split, the speedup is perfect because no inter-processor communication is required.
