Adaptive hp-Refinement for Spectral Elements in Numerical Relativity

Autor: Sarah Renkhoff, Daniela Cors, David Hilditch, Bernd Brügmann

When a numerical simulation has to handle a physics problem with a wide range of time-dependent length scales, dynamically adaptive discretizations can be the method of choice. We present a major upgrade to the numerical relativity code bamps in the

Evolution of Brill waves with an adaptive pseudospectral method

Autor: Isabel Suárez Fernández, Sarah Renkhoff, Daniela Cors Agulló, Bernd Brügmann, David Hilditch

As a first application of the new adaptive mesh functionality of the the pseudospectral numerical relativity code bamps, we evolve twist-free, axisymmetric gravitational waves close to the threshold of collapse. We consider six different one-paramete

Publikováno v: Physical Review D. 103

We present an implementation of the dual foliation generalized harmonic gauge (DF-GHG) formulation within the pseudospectral code bamps. The formalism promises to give greater freedom in the choice of coordinates that can be used in numerical relativ
