Overset Grid Assembler and Flow Solver with Adaptive Spatial Load Balancing

A Solution Adaptive Structured/Unstructured Overset Grid Flow Solver with Applications to Helicopter Rotor Flows

This paper summarizes a method that solves both the three dimensional thin-layer Navier-Stokes equations and the Euler equations using overset structured and solution adaptive unstructured grids with applications to helicopter rotor fiowfields. The overset structured grids use an implicit finite-difference method to solve the thin-layer Navier-Stokes/Euler equations while the unstructured grid ...

Load Balancing Strategies for Multi-Block Overset Grid Applications

The multi-block overset grid method is a powerful technique for high-fidelity computational fluid dynamics (CFD) simulations about complex aerospace configurations. The solution process uses a grid system that discretizes the problem domain by using separately generated but overlapping structured grids that periodically update and exchange boundary information through interpolation. For efficie...

Load-Balancing Remote Spatial Join Queries in a Spatial GRID

The explosive growth of spatial data worldwide coupled with the emergence of GRID computing provides a strong motivation for designing a spatial GRID which allows transparent access to geographically distributed data. While different types of queries may be issued from any node in such a spatial GRID for retrieving the data stored at other (remote) nodes in the GRID, this paper specifically add...

A comparison of some dynamic load-balancing algorithms for a parallel adaptive flow solver

In this paper we contrast the performance of three different parallel dynamic load-balancing algorithms when used in conjunction with a particular parallel, adaptive, time-dependent, 3-d ow solver that has recently been developed at Leeds. An overview of this adaptive solver is given along with a description of a new dynamic load-balancing algorithm. The eeectiveness of this algorithm is then a...
