GiRaFFE: An Open-Source General Relativistic Force-Free Electrodynamics Code
Zachariah B. Etienne, Mew-Bing Wan, Maria C. Babiuc +2
We present GiRaFFE, the first open-source general relativistic force-free electrodynamics (GRFFE) code for dynamical, numerical-relativity generated spacetimes. GiRaFFE adopts the…
Testing the well-posedness of characteristic evolution of scalar waves
M. C. Babiuc, H-O. Kreiss, J. Winicour
Recent results have revealed a critical way in which lower order terms affect the well-posedness of the characteristic initial value problem for the scalar wave equation. The prope…
Binary Black Hole Waveform Extraction at Null Infinity
M. C. Babiuc, J. Winicour, Y. Zlochower
In this work, we present a work in progress towards an efficient and economical computational module which interfaces between Cauchy and characteristic evolution codes. Our goal is…
A Characteristic Extraction Tool for Gravitational Waveforms
M. C. Babiuc, B. Szilagyi, J. Winicour +1
We develop and calibrate a characteristic waveform extraction tool whose major improvements and corrections of prior versions allow satisfaction of the accuracy standards required…
Strategies for the Characteristic Extraction of Gravitational Waveforms
M. C. Babiuc, N. T. Bishop, B. Szilagyi +1
We develop, test and compare new numerical and geometrical methods for improving the accuracy of extracting waveforms using characteristic evolution. The new numerical method invol…
Implementation of standard testbeds for numerical relativity
M. C. Babiuc, S. Husa, D. Alic +8
We discuss results that have been obtained from the implementation of the initial round of testbeds for numerical relativity which was proposed in the first paper of the Apples wit…
