Discontinuous Galerkin method for the spherically reduced BSSN system with second-order operators

Field, Scott E., Hesthaven, Jan S., Lau, Stephen R. et al.

Understand

We present a high-order accurate discontinuous Galerkin method for evolving the spherically-reduced Baumgarte-Shapiro-Shibata-Nakamura (BSSN) system expressed in terms of second-order spatial operators.

  • Our multi-domain method achieves global spectral accuracy and long-time stability on short computational domains.
  • We discuss in detail both our scheme for the BSSN system and its implementation.
  • After a theoretical and computational verification of the proposed scheme, we conclude with a brief discussion of issues likely to arise when one considers the full BSSN system.
