A Discontinuous Galerkin method with a modified penalty flux for the propagation and scattering of acousto-elastic waves
Ruichao Ye, Maarten de Hoop, Christopher Petrovitch +2
We develop an approach for simulating acousto-elastic wave phenomena, including scattering from fluid-solid boundaries, where the solid is allowed to be anisotropic, with the Disco…
Strong Scaling for Numerical Weather Prediction at Petascale with the Atmospheric Model NUMA
Andreas Müller, Michal A. Kopera, Simone Marras +3
Numerical weather prediction (NWP) has proven to be computationally challenging due to its inherent multiscale nature. Currently, the highest resolution NWP models use a horizontal…
Mitigating the Curse of Dimensionality: Sparse Grid Characteristics Method for Optimal Feedback Control and HJB Equations
Wei Kang, Lucas C. Wilcox
We address finding the semi-global solutions to optimal feedback control and the Hamilton--Jacobi--Bellman (HJB) equation. Using the solution of an HJB equation, a feedback optimal…
