Element-by-Element Parallel Computation of Incompressible Navier--Stokes Equations in Three Dimensions

Tony W. H. Sheu, Morten M. T. Wang, S. F. Tsai
1999 SIAM Journal on Scientific Computing  
In the steady-state analysis of Navier-Stokes equations, we adopt the mixed formulation to preserve mass conservation on quadratic elements which accommodate the Ladyzhenskaya-Babǔska-Brezzi (LBB) stability  ...  To this end, our analysis is implemented in shared memory parallel architectures, CRAY C-90 and J-90.  ...  Beyond this, microtasking uses special parallel features of the CRAY C-90. Much improved overall speed-up results are produced as compared with macrotasking.  ...

Computational Aerothermodynamic Design Issues for Hypersonic Vehicles

Peter A. Gnoffo, K. James Weilmuenster, H. Harris Hamilton, David R. Olynick, Ethiraj Venkatapathy
1999 Journal of Spacecraft and Rockets  
The current status of computational aerothermodynamics is then discussed, with emphasis on its capabilities and limitations for contributions to the design process of hypersonic vehicles.  ...  A brief review of the evolutionary progress in computational aerothermodynamics is presented.  ...  A rich variety of options are supported for convergence of both steady and unsteady Navier-Stokes, Thin-Layer Navier-Stokes, Parabolized Navier-Stokes, and Euler equations.  ...
