MHDuet : a high-order General Relativistic Radiation MHD code for CPU and GPU architectures
Carlos Palenzuela, Miguel Bezares, Steven Liebling +12
We present MHDuet, an open source evolution code for general relativistic magnetohydrodynamics with neutrino transport. The code solves the full set of Einstein equations coupled t…
Dynamical shift conditions for the Z4 and BSSN hyperbolic formalisms
C. Bona, C. Palenzuela
A class of dynamical shift conditions is shown to lead to a strongly hyperbolic evolution system, both in the Z4 and in the BSSN Numerical Relativity formalisms. This class general…
A 3+1 covariant suite of Numerical Relativity Evolution Systems
C. Bona, T. Ledvinka, C. Palenzuela
A suite of three evolution systems is presented in the framework of the 3+1 formalism. The first one is of second order in space derivatives and has the same causal structure of th…
The Gravitational Radiaton degrees of freedom in Hyperbolic Systems for Numerical Relativity
C. Bona, C. Palenzuela
The gravitational radiation degrees of freedom of freedom are described in the framework of the 3+1 decomposition of spacetime. The relationship with eigenfields of the Kidder-Sche…
Flux Limiter Methods in 3D Numerical Relativity
C. Bona, C. Palenzuela
New numerical methods have been applied in relativity to obtain a numerical evolution of Einstein equations much more robust and stable. Starting from 3+1 formalism and with the ev…
Robust evolution system for Numerical Relativity
A. Arbona, C. Bona, J. Masso +1
The paper combines theoretical and applied ideas which have been previously considered separately into a single set of evolution equations for Numerical Relativity. New numerical i…
