WebHydrodynamic codes is to solve the Euler or Navier-Stokes equations, which describe the time evolution of uid parameters as a set of rst order di erential equations. For the purpose of my code, we will focus on the Euler equations. These equations are a result of the three conservation laws, and are described below. Conservation of Mass: @ˆ @t
