Load Balancing Unstructured Adaptive Grids for CFD Problems

Mesh adapt(on is a powerful tool for efficient unstructured-grid computations but causes load imbalance among processors on a parallel machine. A dynamic load balancing method is presented that balances the workload across all processors with a global view. After each parallel tetrahedral mesh adapt(on, the method first determines if the new mesh is sufficiently unbalanced to warrant a repartit...

Parallel Ocean Flow Computations on a Regular and on an Irregular Grid

Ocean ow problems can be discretized and solved on a regular grid, by taking land points into account in the computations, or on an irregular grid. In the latter approach, the number of unknowns is less than for the regular grid. The data structures are completely di erent for the two approaches. As a consequence, di erent numerical techniques may be required. In this paper we study di erent pr...

Hypersonic Flow Computations on Unstructured Meshes

A method for computing inviscid hypersonic ow over complex con gurations using unstructuredmeshes is presented. The unstructured grid solver uses an edge{based nite{volume formulation. Fluxes are computed using a ux vector splitting scheme that is capable of representing constant enthalpy solutions. Second{order accuracy in smooth ow regions is obtained by linearly reconstructing the solution, ...

Transonic Turbulent Flow Computations on Unstructured Triangular Grids

High-reynolds Number Viscous Flow Computations Using an Unstructured-grid Method

An unstructured grid method is presented to compute three-dimensional compressible turbulent flows for complex geometries. The Navier-Stokes equations along with the one equation turbulence model of Spalart-Allmaras are solved using a parallel, matrix-free implicit method on unstructured tetrahedral grids. The developed method has been used to predict drags in the transonic regime for both DLRF...
