WebThe NPNS system is nonlinear, and the blocking boundary conditions are nonlinear and nonlocal. While blocking boundary conditions lead to stable conﬁgurations, instabilities occur for selective boundary con-ditions. These have been studied in simpliﬁed models mathematically and numerically ([18], [22]) and observed in physical experiments [17].
