In this example we use CentPack's one-dimensional second order fully-discrete formulation, centpack_1d_FD2, to evolve the solution of the equations of Ideal Magnetohydrodynamics
stands for the total pressure, and the the pressure, p, is related to the conserved quantities through the equation of state
with . The solution is calculated over the domain , from , to . The initial conditions are those of the Brio-Wu shock tube
and Dirichlet boundary conditions (i.e., the conserved quantities take on the values specified by the initial conditions at either boundary). Solution computed with 400 cells and cfl number 0.475.
