Dynamical Gauge Equations

This version uses dynamical gauge variables, so there are several more equations to code as well.

Initial Conditions for Head-On Collision of Two Non-spinning Black Holes

Additionally, for this example, since this is a head-on collision of two non-spinning black holes, our initial conformal parameter will be calculated as:

Where  m_i is the mass associated with each black hole, is the initial location of each black hole and the location of  each point is

Kreiss-Oliger Spatial Filtering

Because of high frequency numerical noise, this version also includes Kriess-Oliger spatial filtering. This filter is implemented as:
