Towards Adaptive Simulations of Dispersive Tsunami Propagation from an Asteroid Impact
Marsha J. Berger, Randall J. LeVeque
The long-term goal of this work is the development of high-fidelity simulation tools for dispersive tsunami propagation. A dispersive model is especially important for short wavele…
Efficient Tsunami Modeling on Adaptive Grids with Graphics Processing Units (GPUs)
Xinsheng Qin, Randall LeVeque, Michael Motley
Solving the shallow water equations efficiently is critical to the study of natural hazards induced by tsunami and storm surge, since it provides more response time in an early war…
Shoaling on Steep Continental Slopes: Relating Transmission and Reflection Coefficients to Green's Law
Jithin D. George, David I. Ketcheson, Randall J. LeVeque
The propagation of long waves onto a continental shelf is of great interest in tsunami modeling and other applications where understanding the amplification of waves during shoalin…
A path integral method for solution of the wave equation with continuously-varying coefficients
Jithin D. George, David I. Ketcheson, Randall J. LeVeque
A new method of solution is proposed for solution of the wave equation in one space dimension with continuously-varying coefficients. By considering all paths along which informati…
Accelerating wave-propagation algorithms with adaptive mesh refinement using the Graphics Processing Unit (GPU)
Xinsheng Qin, Randall J. LeVeque, Michael R. Motley
Clawpack is a library for solving nonlinear hyperbolic partial differential equations using high-resolution finite volume methods based on Riemann solvers and limiters. It supports…
