Geometrically motivated hyperbolic coordinate conditions for numerical relativity: Analysis, issues and implementations
Carles Bona, Luis Lehner, Carlos Palenzuela-Luque
We study the implications of adopting hyperbolic driver coordinate conditions motivated by geometrical considerations. In particular, conditions that minimize the rate of change of…
Almost-stationary motions and gauge conditions in General Relativity
C. Bona, J. Carot, C. Palenzuela-Luque
An almost-stationary gauge condition is proposed with a view to Numerical Relativity applications. The time lines are defined as the integral curves of the timelike solutions of th…
Constraint-preserving boundary conditions in the Z4 Numerical Relativity formalism
C. Bona, T. Ledvinka, C. Palenzuela-Luque +1
The constraint-preserving approach, which aim is to provide consistent boundary conditions for Numerical Relativity simulations, is discussed in parallel with other recent developm…
Gauge pathologies in singularity-avoidant spacetime foliations
C. Bona, T. Ledvinka, C. Palenzuela-Luque +2
The family of generalized-harmonic gauge conditions, which is currently used in Numerical Relativity for its singularity-avoidant behavior, is analyzed by looking for pathologies o…
