## Black hole Collisions

Code Generation and Simulation of the Spacetime Evolution of Black Hole Mergers

**STvAR**package, designed for converting symbolic/tensorial forms to executable code for AMReX.

The STvAR package was inspired by Professor Zach Etienne and the
** NRPy+ ** project at West Virginia University.

## Black Hole Advertising

Simulation of Large Systems of Black Holes with Heavily Designed Initial Conditions

The video shows the simulation of
a very large system of black holes, starting from heavily designed initial conditions using
the **
STvAR ** package. The entire video is run in reverse.
