evolve()

Evolve the equations of compressible hydrodynamics through a timestep dt.

initialize(ng=5)

preevolve()

Since we are 4th order accurate we need to make sure that we initialized with accurate zone-averages, so the preevolve for this solver assumes that the initialization was done to cell-centers and converts it to cell-averages.

substep(myd)

compute the advective source term for the given state
