Class Documentation

class OneDimensionalTimeDependentShock : public AdvectionField

Advection field in x-direction with shock at x = x0 that propagates with a constant speed vsh = v_up - v_down and width x_sh approximated by a tanh() with variable compression ratio r_comp = v_up/v_down. Pre- and postshock speeds as well as shock speed must be specified. The shock position at t=0 can be specified, as well as the time t0 the shock starts to propagate.
