The Hyperboloidal Numerical Evolution of a Good-Bad-Ugly Wave Equation
Edgar Gasperin, Shalabh Gautam, David Hilditch +1
One method for the numerical treatment of future null-infinity is to decouple coordinates from the tensor basis and choose each in a careful manner. This dual-frame approach is ham…

Spherical symmetry as a test case for unconstrained hyperboloidal evolution II: gauge conditions
Alex Vañó-Viñuales, Sascha Husa
We present numerical solutions of the hyperboloidal initial value problem for a self-gravitating scalar field in spherical symmetry, using a variety of standard hyperbolic slicing…
