This work presents a generalization of the Kraynik-Reinelt (KR) boundary conditions for nonequilibrium molecular dynamics simulations. In the simulation of steady, homogeneous flows with periodic boundary conditions, the simulation box deforms with the flow, and it is possible for image particles to become arbitrarily close, causing a breakdown in the simulation. The KR boundary conditions avoid this problem for planar elongational flow and general planar mixed flow [T. A. Hunt, S. Bernardi…

This work generalizes the iterative conformational averaging method to flowing semidilute solutions by introducing a conformation dependent diffusion tensor and a strain dependent approximation to the conformationally averaged Brownian noise and finds that this approach nearly quantitatively reproduces both transient and steady state polymer dynamics and rheology while achieving an order of magnitude computational acceleration.

Investigation of the interplay of deformation and confinement on BCP morphology by varying the simulation strain rate and diameter shows that for low strain rates, near-equilibrium morphology can form despite the deformation, while for progressively higher strain rate, extra lamellae and disordered morphologies appear.
