Radial velocity profiles for the standard model st26gm07n001. Left: snapshots of the spherically averaged radial velocity as a function of the radial distance, covering 4 yr of simulated time (about three pulsation cycles). Right: radial velocity computed at each cell of the computational box determined from a snapshot at time t = 14.2 [yr], presented to show the number of points (N) having the radial velocity at a certain distance from the centre of the box. The vertical lines mark the location of the stellar radius.
