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…

Multidomain Galerkin-Collocation method: spherical collapse of scalar fields II
M. A. Alcoforado, R. F. Aranha, W. O. Barreto +1
We follow the strategy initiated in Ref. [1] and proceed with the implementation of the Galerkin-Collocation domain decomposition (GCDD) applied to the dynamics of a spherical self…

Rio: A new computational framework for accurate initial data of binary black holes
W. Barreto, P. C. M. Clemente, H. P. de Oliveira +1
We present a computational framework (Rio) in the ADM 3+1 approach for numerical relativity. This work enables us to carry out high resolution calculations for initial data of two…
