Workshop on High-Order Methods and High-Fidelity Simulations |
|
Dates: November 6-7, 2006
Location: NIA Headquarters, 100 Exploration Way, Hampton, Virginia
Description:
This workshop focuses on high-order methods and the high-fidelity flow simulations for which these methods may be suited. Compared to its low-order counterparts, high-order methods enjoy their success in numerical simulations that require high temporal and spatial resolutions. This workshop has two primary goals: 1) review the state of the art and present new approaches for high-order discretizations and solution methodologies; 2) to present efforts involving large scale simulations in which either issues of physical modeling or simply the shear size of the physical problem presents a challenge to existing computational methodologies. In addition to invited presentations, a round-table discussion will be held to lay out issues and future directions of high-order methods for improving the state of high-fidelity flow simulations.
The invited speakers cover a broad range of expertise and experience in numerical algorithms, physical modeling, and high-fidelity simulations including: classical spectral and finite-difference methods, more contemporary methods such as discontinuous Galerkin, spectral difference and Conservation Element Solution Element (CESE); structured and unstructured grid methods; Krylov, multi-grid, iterative, preconditioning and sparse matrix methodologies; turbulence modeling, LES/DNS modeling and simulations.
Workshop Agenda: Registration and continental breakfast will begin at 8:00am with opening remarks following at 8:30am.
