SphericalNR

Vassilios Mewes (ORNL)

Abstract: ${\tt SphericalNR}$ is a new dynamical spacetime and general relativistic MHD evolution framework in spherical coordinates for the ${\tt Einstein Toolkit}$. This talk will present the framework, highlighting algorithmic developments to solve hyperbolic PDEs in spherical coordinates within the Cartesian code base of the ${\tt Einstein Toolkit}$ as well as recent developments, including higher order reconstruction methods and an improved atmosphere treatment.
