One Dimensional Ideal MHD Equations

In this example we use a one-dimensional second order fully-discrete central scheme 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.
