A 50mm droplet of liquid aluminum alloy impacts a flat surface at 10 m/s. The surface has two distinct wetting conditions: a static contact angle of 40 degrees on the gray surface and a pinned contact line on the orange surface. The simulation demonstrates the rolling motion of fluid over the pinned contact line, the resulting distortion of the droplet shape, and jetting near the interface between the two surface types.
