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…
