We present a new formulation of the Einstein equations that casts them in an explicitly first order, flux-conservative, hyperbolic form. We show that this now can be done for a wide class of time slicing conditions, including maximal slicing, making it potentially very useful for numerical relativity. This development permits the application to the Einstein equations of advanced numerical methods developed to solve the fluid dynamic equations, {\em without} overly restricting the time slicing…

Lattice Boltzmann model for numerical relativity.

- 2016

This work constructs a lattice Boltzmann model for numerical relativity and validate it with well-established tests, and finds that by increasing the relaxation time, the model gains stability at the cost of losing accuracy, and by decreasing the lattice spacings, the accuracy and stability of the simulations improve.
