TITLE: Automation of Large-Scale Simulations with Emphasis
on a Flexible Discontinuous Galerkin Procedure
ABSTRACT
The first part of this presentation will overview the components of
software systems for automating the simulation of problems defined
over three-dimensional domains. Basic system components include (i)
geometry-based problem definitions, (ii) automatic mesh generation and
adaptation procedures and (iii) a flexible simulation framework that
effectively supports high order discretization processes. The second
part of the presentation will discuss the development of a discontinuous
Galerkin procedure within this simulation framework. The p-version
discontinuous Galerkin discretizations coupled an Algorithm Oriented
Mesh Datastructure (AOMD) provides a flexible discretization technology
that can be used to perform adaptive simulation on general unstructured
meshes while being able to operate efficiently on highly structured
spatial decompositions. Parallel adaptive results for these procedures
applied to basic fluid instability problems will be presented.
