3D matter evolution with the Z4 formulation — •Marcus Thierfelder1, Wolfgang Tichy2, Sebastiano Bernuzzi1, Roman Gold1, David Hilditch1, and Bernd Brügmann1 — 1Theoretisch-Physikalisches Institut, FSU Jena, Germany — 2Department of Physics, Florida Atlantic University, USA
Several promising tests in spherical symmetry have shown that the evolution with a conformal decomposition of a Z4-like formulation (Z4c) of General Relativity shows advantages in comparison with the BSSNOK formalism. We compare evolutions of both systems in full 3D for puncture and neutron star initial data.
