Second-order slope limiters for the simultaneous linear advection of (not so) independent variables
Quang Huy Tran
Abstract: We propose a strategy to perform second-order enhancement using slope-limiters for the simultaneous linear advection of several scalar variables. Our strategy ensures a discrete min-max principle not only for each variable but also for any number of non-trivial combinations of them, which represent control variables. This problem arises in fluid mechanics codes using the Arbitrary Lagrange–Euler formalism, where the additional monotonicity property on control variables is required by physical considerations within the remap step.
