A Comparison of High Order Interpolation Nodes for the Pyramid
Jesse Chan, T. Warburton
The use of pyramid elements is crucial to the construction of efficient hex-dominant meshes. For conforming nodal finite element methods with mixed element types, it is advantageou…
High-Order Finite-differences on multi-threaded architectures using OCCA
David S. Medina, Amik St-Cyr, Timothy Warburton
High-order finite-difference methods are commonly used in wave propagators for industrial subsurface imaging algorithms. Computational aspects of the reduced linear elastic vertica…
Residual based adaptivity and PWDG methods for the Helmholtz equation
Shelvean Kapita, Peter Monk, T. Warburton
We present a study of two residual a posteriori error indicators for the Plane Wave Discontinuous Galerkin (PWDG) method for the Helmholtz equation. In particular we study the h-ve…
GPU Accelerated Discontinuous Galerkin Methods for Shallow Water Equations
R Gandham, D S Medina, T Warburton
We discuss the development, verification, and performance of a GPU accelerated discontinuous Galerkin method for the solutions of two dimensional nonlinear shallow water equations.…
OCCA: A unified approach to multi-threading languages
David S Medina, Amik St-Cyr, T. Warburton
The inability to predict lasting languages and architectures led us to develop OCCA, a C++ library focused on host-device interaction. Using run-time compilation and macro expansio…
