In the history of numerical (or computational) general relativity, the “Frontiers” meeting in 1988 at the University of Illinois, Urbana-Champaign (USA), played a pivotal role in establishing numerical relativity as a major topic in computational physics and simulation science. The “New Frontiers” meeting in 2006 at the AEI Potsdam convened following major breakthroughs in numerical … Continue reading New Frontiers 2025: past, current and future challenges in Numerical Relativity
