- W2013007686 abstract "The Baumgarte-Shapiro-Shibata-Nakamura (BSSN) formulation of the 3+1 evolution equations of General Relativity has proven to be very robust in full three-dimensional simulations. However there are many astrophysical phenomena that are axisymmetric and doesn't require so many computational resources to be studied. When considering axisymmetric systems special care is needed since the adapted coordinates are non-trivial and singular on the axis, a fact that may lead to numerical instabilities. In this work we analyze a generalized version of the BSSN system adapted to axisymmetric spacetimes and show a regularization procedure that renders the evolution equations explicitly regular." @default.
