Snapshot: different types of structured jets (H, T, P, and HL) with an injected perturbation. The generated moving shock wave is located at ∼135 R_jet from the base. The propagation of the jet is going from left to right along the increasing value of Z. For each case, the density contour (in log-scale) is drawn on the bottom side and the thermal energy contour on the top side. Units on x and y-axis in R_jet unit.
