| Summary: | This thesis presents work in the area of mesh generation for large scale and complex computational simulation. The work covers two areas of great interest within the field of mesh generation; anisotropic mesh generation and parallel large scale mesh generation. Examples of anisotropic Delaunay mesh generation are presented with application to fluid dynamics and computational electromagnetic scattering simulations. Results are shown with reference to simulation accuracy and computational efficiency. Research into parallel mesh generation is presented and a method of parallel Delaunay mesh generation suitable for use on distributed and shared memory parallel computers is described. Results are shown with reference to computational efficiency, memory usage and finale mesh quality. Examples of meshes generated in parallel are shown for both computational fluid dynamics simulations on simple aeronautical geometries to full aircraft and computational electromagnetic scattering simulations on full aircraft. The meshes range in size from a few thousand tetrahedral elements to a mesh for a computational electromagnetic simulation containing approximately one billion tetrahedral elements. |
