High-Order and High Accurate CFD Methods and Their Applications for Complex Grid Problems
The purpose of this article is to summarize our recent progress in high-order and high accurate CFD methods for flow problems with complex grids as well as to discuss the engineering prospects in using these methods. Despite the rapid development of high-order algorithms in CFD, the applications of high-order and high accurate methods on complex configurations are still limited. One of the main...
متن کاملHigh-Order Discontinuous Galerkin Methods for CFD
In recent years it has become clear that the current computational methods for scientific and engineering phenomena are inadequate for many challenging problems. Examples of these problems are wave propagation, turbulent fluid flow, as well as problems involving nonlinear interactions and multiple scales. This has resulted in a significant interest in so-called high-order accurate methods, whic...
متن کاملHigh order ILU preconditioners for CFD problems
This paper tests a number of ILU-type preconditioners for solving indeenite linear systems which arise from complex applications such as Computational Fluid Dynamics. Both point and block preconditioners are considered. The paper focuses on ILU factorization which can be computed with high accuracy by allowing liberal amounts of ll-in. A number of strategies for enhancing the stability of the f...
متن کاملVisualization for High - Order Discontinuous Galerkin CFD
This thesis demonstrates a technique that reduces the perceived error introduced in the visualization of higher-order DG solutions with traditional tools. Most visualization techniques work by using the solution at the mesh vertices and linearly interpolating to color the interior of the element. For higher-order solutions (where the visualization mesh is the same as the solution mesh) this met...
متن کاملA High-Order Accurate Parallel Solver for Maxwell's Equations on Overlapping Grids
A scheme for the solution of the time dependent Maxwell’s equations on composite overlapping grids is described. The method uses high-order accurate approximations in space and time for Maxwell’s equations written as a second-order vector wave equation. High-order accurate symmetric difference approximations to the generalized Laplace operator are constructed for curvilinear component grids. Th...
