Horizontal view at depths of 200 and 400 km of flow around the slab edges for the cases of (a) retreating trench, (b) fixed trench and (c) advancing trench. Temperature and velocity fields are shown in the area near the subducting slab. An equidistant cylindrical projection is used. Note that the scale of the velocity vectors is different in each figure. The time elapsed from the start of calculations is (a) 7.39 Myr, (b) 7.62 Myr, and (c) 5.79 Myr, respectively.
