Evolution of a 1D sinusoid of CR energy density with streaming advection only as a function of position with 512 cells and imposing a constant Alfvén velocity of 1. The solution is made of two plateaus as the maxima are capped over time, due to the infinite streaming diffusion coefficient, while the two regions between the two plateaus move at a velocity of ± γCR = ±1.4.
