Fig. 7.. Evolution of s-l interface of a growing circular grain: (a) moving grain driven by uniformly imposed flow field v = (1, 1) W0/τ0 (when t < 128 τ0) and -v (when t > 128 τ0); (b) motionless grain; (c) comparison between the final interfaces in two cases. The domain was l × l with l = 256 W0 and the initial radius was 25 W0 (blue interface: moving grain; red interface: motionless grain). The crosses indicate where the grain should have been centered. O1 : (0.25, 0.25) l, O2 : (0.75, 0.75) l.
