**Run a hydrodynamic code for:**

   - Read the [[http://astro.physics.ncsu.edu/pub/VH-1/bproblems.php|Problems & Solutions]] guide.
    - Set up and run the [[http://astro.physics.ncsu.edu/pub/VH-1/bproblems.php#stb|Sedov Blast]] problem.
    - Set up and run the [[http://astro.physics.ncsu.edu/pub/VH-1/bproblems.php#bnd|Bondi Accretion]] problem.

You can also try:
   - 	Gravitational collapse of:
    *	Uniformly distributed “star” (P(initial) = 0)
    *	Simple density profile (P(initial) = 0)
    *	Are there self-similar solutions?
   -	Energy injection into gas clump of:
    *	uniformly distributed mass
    *	simple density profile $\rho(r) = \rho(0)[1-(r/R)^2]^n $
    *	How does the evolution change with different injection energies
   -	Drive a piston through some medium
    *	Piston in a cylinder
    *	Spherical piston driving outwards
    *	Spherical piston driving inwards
    *	How does the outward driven spherical piston compare to the energy injection?
