FIG. 1.

Internal (blue) and external (green, large fluctuations) pressure as a function of the number of collision steps . The collision time is and the time .

FIG. 2.

Illustration of the random shift and the distribution of particles in collision cells cut by the walls. The walls are located at . Under shear, the walls move with the velocities . The phantom particles are located in the centers of the truncated parts of the collision cells at and , respectively. They move with the velocities and , respectively. The dashed-dotted line indicates the linear velocity profile.

FIG. 3.

Internal (blue) and external (green, large fluctuations) stress tensor as a function of the number of collision steps. The collision time is . At , the system is in a stationary state.

FIG. 4.

Viscosities determined via the internal (bullets) and external (open squares) stress tensors for a system confined between walls as a function of the collision time. The analytical results for the total (black, top), the kinetic (red, ), and collisional (blue, ) contributions are presented by solid lines.
