Typical system for moving contact line problem.
Simulation system geometry. The origin of axis is at the receding contact line of fluid 2 and axis at the initial position of inner wall atoms.
Direction of wall lattice. The wall consists of two layers of bcc lattice. Larger circle: innermost layer contacting with fluid; smaller circle: outer layer.
