Equivalence of nonequilibrium algorithms for simulations of planar Couette flow in confined fluids.
Shear flow in fluids confined between planar solid walls is conventionally simulated by moving the walls past each other at constant relative velocity. In infinite fluids (in periodic boundary conditions), it is simulated using one of the "synthetic" nonequilibrium algorithms (the so-called Sllod and Dolls algorithms). Here I formulate the boundary conditions for the motion of confining walls that make these three algorithms equivalent in the weak-field limit.
