 +11. Last exercise: 2-D Sedov Taylor Blast Wave. Define a 2-D **periodic** grid of variables (rho, rho_u, rho_v, E). Set P = e = 1e-5, rho_u = rho_v = 0, and rho = 1.0 everywhere (Note: gamma = 2). Set one cell (either in the corner, or center of the grid) to have e = 1. Adapt the timestep delta_t at each step to satisfy the Courant condition (given by the maximum of D_max across the grid). The timestep should be very small at first and increase with time as the shock wave expands.
