Nyquist-resolving gravitational waves via orbital frequency-based refinement
William K. Black, David Neilsen, Eric W. Hirschmann +2
Adaptive mesh refinement efficiently facilitates the computation of gravitational waveforms in numerical relativity. However, determining precisely when, where, and to what extent…
Massively parallel simulations of binary black holes with Dendro-GR
Milinda Fernando, David Neilsen, Yosef Zlochower +2
We present results from the new Dendro-GR code. These include simulations of binary black hole mergers for mass ratios up to q=16. Dendro-GR uses Wavelet Adaptive Multi-Resolution…
Scalable adaptive PDE solvers in arbitrary domains
Kumar Saurabh, Masado Ishii, Milinda Fernando +6
Efficiently and accurately simulating partial differential equations (PDEs) in and around arbitrarily defined geometries, especially with high levels of adaptivity, has significant…
Scalable Local Timestepping on Octree Grids
Milinda Fernando, Hari Sundar
Numerical solutions of hyperbolic partial differential equations(PDEs) are ubiquitous in science and engineering. Method of lines is a popular approach to discretize PDEs defined i…
Massively Parallel Simulations of Binary Black Hole Intermediate-Mass-Ratio Inspirals
Milinda Fernando, David Neilsen, Hyun Lim +2
We present a highly-scalable framework that targets problems of interest to the numerical relativity and broader astrophysics communities. This framework combines a parallel octree…
