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.
