Notes. Number of grid zones, wedge size w, grid resolution in r, $\theta$ and $\phi$ direction, estimated Reynolds numbers $R_{\rm e1}$ , $R_{\rm e2}$ , characteristic flow velocities, $v_{\rm c1}$ and $v_{\rm c2}$ , and typical convective turnover timescales, $\tau_{\rm cnv1}$ and $\tau_{\rm cnv2}$ , for the CVZ-1 and CVZ-2 part of the convection zone, respectively. $t_{\rm max}$ is the maximum evolution time.
