### From square patch to datacube

The square patch is now a cube 500 million light years on a side. In this
calculation, the cube is subdivided into a network of 134 million smaller
cubes roughly one million light years on a side. In each cell we solve the
equations of hydrodynamics to predict the behavior of the gas density,
pressure, temperature and velocity.
