Figure 3: Analytical pressure, density and flow velocity profiles at t = 0.4 for the relativistic Riemann problem with initial data  = 10³,  = 1.0,  = 0.0, and  = 10^–2,  = 1.0,  = 0.0, varying the values of the tangential velocities. From left to right,  = 0, 0.9, 0.99 and from top to bottom  =0, 0.9, 0.99. An ideal EOS with  = 5/3 was assumed.
