The Bondi problem revisited: a spectral domain decomposition code
M. A. Alcoforado, W. O. Barreto, H. P. de Oliveira
We present a simple domain decomposition code based on the Galerkin-Collocation method to integrate the field equations of the Bondi problem. The algorithm is stable, exhibits expo…

New numerical framework for the generalized Baumgarte-Shapiro-Shibata-Nakamura formulation: The vacuum case for spherical symmetry
M. A. Alcoforado, R. F. Aranha, W. O. Barreto +1
Here we report a developed high performance and simplified version of the code denominated RIO, which can be easily extended, for the generalized BSSN formulation. We implement a c…

Acceptability Conditions and Relativistic Anisotropic Generalized Polytropes
Daniel Suárez-Urango, J. Ospino, Héctor Hernández +1
This paper explored the physical acceptability conditions for anisotropic matter configurations in General Relativity. The study considered a generalized polytropic equation of sta…
