Absolute value of radial velocity for the model FMH1_m4. The white contours highlight the tracer values at levels of 0.2, 0.4, 0.6, and 0.8 (the tracer levels are in decreasing order, i.e., from 0.8 to 0.2, from left to right). Outside of the jet structure delineated by the shear layer (white contours), the velocity is smaller than 0.01 everywhere in the grid, meaning that this can be considered a steady solution.
