openGR: An Infrastructure for Numerical Relativity

ORAL

Abstract

We present the current state of the code {\it openGR}, which is a modular, open framework developed to carry out simulations of binary black hole mergers. While designed with the two-body problem in mind, {\it openGR} will evolve most general vacuum spacetimes. The code is based on the adaptive mesh refinement library \texttt{SAMRAI}. We describe the main features of the code and give the results of simulations of head-on binary black hole mergers. We will discuss the scaling properties of {\it openGR} and its overall status. The code will be made publicly available.
