Optimal control using flux potentials: A way to construct bound-preserving finite element schemes for conservation laws

Falko Ruppenthal, Dmitri Kuzmin

To ensure preservation of local or global bounds for numerical solutions of conservation laws, we constrain a baseline finite element discretization using optimization-based (OB) f…

Analysis of algebraic flux correction for semi-discrete advection problems

Hennes Hajduk, Andreas Rupp, Dmitri Kuzmin

We present stability and error analysis for algebraic flux correction schemes based on monolithic convex limiting. For a continuous finite element discretization of the time-depend…

A new perspective on flux and slope limiting in discontinuous Galerkin methods for hyperbolic conservation laws

Dmitri Kuzmin

In this work, we discuss and develop multidimensional limiting techniques for discontinuous Galerkin (DG) discretizations of scalar hyperbolic problems. To ensure that each cell av…

Algebraic entropy fixes and convex limiting for continuous finite element discretizations of scalar hyperbolic conservation laws

Dmitri Kuzmin, Manuel Quezada de Luna

In this work, we modify a continuous Galerkin discretization of a scalar hyperbolic conservation law using new algebraic correction procedures. Discrete entropy conditions are used…
