KAUST-IAMCS Workshop on Multiscale Modeling, Advanced Discretization Techniques, and Simulation of Wave Propagation

May 7–8, 2011
King Abdullah University of Science and Technology (KAUST)
Thuwal, Saudi Arabia

Description

Robust and accurate simulations of wave propagation in complex media are essential for many important industrial applications ranging from seismic imaging to medical tomography. Challenges in this area include developing robust discretization techniques that are accurate, less sensitive to wave number, and are scalable on state-of-the-art computer architectures. The focus areas of this workshop are:

Advanced discretization techniques
Wave propagation in heterogeneous and random media
Subgrid models, multiscale discretization techniques, and uncertainty quantification
Solvers
Applications to geophysics
High-performance computation and visualization tools for large-scale wave simulations

This workshop will bring together researchers from academia and industry, with the goal of facilitating the exchange of ideas to improve modeling and simulation predictions. The workshop will consist of a number of invited presentations. In addition, we particularly encourage poster presentations from workshop participants.

The workshop will be hosted by the KAUST Global Collaborative Research (GCR) at King Abdullah University of Science and Technology (KAUST) in Thuwal, Saudi Arabia. The location, schedules, and facilities will allow for plenty of interactions among participants. Support will be provided by a mixture of funds from KAUST, GCR, Texas A&M University's Institute for Applied Mathematics and Computational Science (IAMCS), and Texas A&M's Institute for Scientific Computation (ISC). There is no registration fee. Interested participants should contact KAUSTwaveprop@gmail.com for information and assistance with registration, accommodations, or airport transfer. Information will be provided at http://isc.tamu.edu/events/KAUSTwaveprop/ and will be updated frequently.
