The ionized fluid can move along the magnetic field lines, while it interacts with the neutral fluid via ion-neutral elastic scattering. I use an explicitly flux-conserving two-dimensional Eulerian flux-corrected transport code to study the dynamics of two-fluid shocks. A numerical instability intrinsic to two-fluid problems was discovered, and a solution to the problem is proposed. The code can successfully simulate C-type shocks. The results of the linear stability analysis by Wardle are confirmed, and the nonlinear behavior of the instability is explored.
