Spherical Evolution of the Generalized Harmonic Gauge Formulation of General Relativity on Compactified Hyperboloidal Slices
Christian Peterson, Shalabh Gautam, Alex Vañó-Viñuales +1
We report on the successful numerical evolution of the compactified hyperboloidal initial value problem in general relativity using generalized harmonic gauge. We work in spherical…

Summation by Parts and Truncation Error Matching on Hyperboloidal Slices
Shalabh Gautam, Alex Vañó-Viñuales, David Hilditch +1
We examine stability of summation by parts (SBP) numerical schemes that use hyperboloidal slices to include future null infinity in the computational domain. This inclusion serves…
