Parallel Mesh Adaptive Techniques for Complex Flow Simulation: Geometry Conservation

Racoon: A parallel mesh-adaptive framework for hyperbolic conservation laws

We report on the development of a computational framework for the parallel, mesh-adaptive solution of systems of hyperbolic conservation laws like the timedependent Euler equations in compressible gas dynamics or Magneto-Hydrodynamics (MHD) and similar models in plasma physics. Local mesh refinement is realized by the recursive bisection of grid blocks along each spatial dimension, implemented ...

Adaptive Parallel Meshes with Complex Geometry

We discuss the automatic creation and adaptive refinement of an unstructured mesh within a complex geometry such as the space surrounding an airplane. This may be formulated as two distinct parts; a non-parallel part requiring global knowledge which automatically creates a coarse compatible mesh, and a parallel local refinement algorithm, which refines the mesh until simulation can begin, then ...

Parallel Adaptive hp - Refinement Techniques for Conservation Laws *

Abstract We describe an adaptive hp-refinement local finite element procedure for the parallel solution of hyperbolic systems of conservation laws on rectangular domains. The local finite element procedure utilizes spaces of piecewise-continuous polynomials of arbitrary degree and coordinated explicit Runge-Kutta temporal integration. A solution limiting procedure produces monotonic solutions n...

Toward Parallel, Adaptive Mesh Refinement for Chemically Reacting Flow Simulations1

Adaptive numerical methods offer greater efficiency than traditional numerical methods by concentrating computational effort in regions of the problem domain where the solution is difficult to obtain. In this paper, we describe progress toward adding mesh refinement to MPSalsa, a computer program developed at Sandia National Laboratories to solve coupled three-dimensional fluid flow and detaile...
