A magnetohydrodynamic particle code is used to simulate highly nonlinear stages of the Kelvin--Helmholtz instability. Without a magnetic field, a supersonic flow with sonic Mach number M/sub s/ creates a stream of vortices which turn into a series of structured shock fronts with shock angle sin/sup -1/ (1/M/sub s/). With a magnetic field, a super-Alfvenic flow results in substantial bending of the magnetic field lines.
