会议概要

Workshop Title:

Active Flux Methods: Development and Applications

Dates:

December 6-8, 2025

Description:

This workshop will bring together researchers working on the development, analysis, and application of Active Flux (AF) methods—a class of numerical schemes for hyperbolic partial differential equations that combine high-order accuracy, robustness, and conservation with novel reconstruction strategies. Originating as an alternative to classical finite volume and discontinuous Galerkin methods, AF schemes utilize pointwise degrees of freedom at cell interfaces, evolved through exact or approximate evolution operators, which yield significant advantages in capturing wave phenomena and reducing numerical dissipation.

The goals of the workshop are:

To survey recent advances in the design and analysis of AF methods, including their extensions to systems with source terms, nonconservative structures, and stiff regimes.
To discuss new strategies for reconstruction, stability enhancement, and adaptivity within the AF framework.
To showcase emerging applications of AF methods in fields such as fluid dynamics, magnetohydrodynamics, plasma physics, shallow water, and others
To foster interdisciplinary collaboration between developers of numerical methods and researchers working on complex physical systems where AF schemes can provide tangible benefits.

Topics may include (but are not limited to):

Active Flux methods for linear and nonlinear hyperbolic systems
Extensions to multidimensional, nonconservative, or coupled systems
Structure-preserving and asymptotic-preserving formulations
Treatment of boundary conditions and complex geometries
Comparison with traditional high-order methods
Applications to compressible flows, low Mach number regimes, and multiphysics models
Implementation strategies and computational efficiency

The workshop will include invited talks, contributed presentations, and free discussions to foster the exchange of ideas and explore future directions in this rapidly evolving field.
