Description
In a series of previous works, several initial boundary value problems in numerical relativity were demonstrated as numerically stable even with boundaries placed in the strongly gravitating region of a dynamical spacetime. Now, care is being taken to define boundary conditions that can be placed on the radiating degrees of freedom based on quasi-local conservation laws. Incoming gravitational waves can be set by controlling the flux of quasi-local quantities, leading to a boundary condition framework first order in derivatives of the metric and with a physical interpretation valid in any location in a dynamical spacetime.
