Discontinuous Galerkin method for linear wave equations involving derivatives of the Dirac delta distribution
Scott E. Field, Sigal Gottlieb, Gaurav Khanna +1
Linear wave equations sourced by a Dirac delta distribution and its derivative(s) can serve as a model for many different phenomena. We describe a discontinuous Galerkin (DG…
A GPU-accelerated mixed-precision WENO method for extremal black hole and gravitational wave physics computations
Scott E. Field, Sigal Gottlieb, Zachary J. Grant +2
We develop and use a novel mixed-precision weighted essentially non-oscillatory (WENO) method for solving the Teukolsky equation, which arises when modeling perturbations of Kerr b…
Fast evaluation of far-field signals for time-domain wave propagation
Scott E. Field, Stephen R. Lau
Time-domain simulation of wave phenomena on a finite computational domain often requires a fictitious outer boundary. An important practical issue is the specification of appropria…
Two-step greedy algorithm for reduced order quadratures
Harbir Antil, Scott E. Field, Frank Herrmann +2
We present an algorithm to generate application-specific, global reduced order quadratures (ROQ) for multiple fast evaluations of weighted inner products between parameterized func…
