Neural network based limiter with transfer learning
Maria Han Veiga, Rémi Abgrall
A neural network is trained using simulation data from a Runge Kutta discontinuous Galerkin (RKDG) method and a modal high order limiter. With this methodology, we design one and t…
Analysis of the SBP-SAT Stabilization for Finite Element Methods Part II: Entropy Stability
Rémi Abgrall, Jan Nordström, Philipp Öffner +1
In the research community, there exists the strong belief that a continuous Galerkin scheme is notoriously unstable and additional stabilization terms have to be added to guarantee…
General polytopal H(div) conformal finite elements and their discretisation spaces
Rémi Abgrall, Élise Le Mélédo, Philipp Öffner
We present a class of discretisation spaces and H(div)-conformal elements that can be built on any polytope. Bridging the flexibility of the Virtual Element spaces towards the elem…
A class of finite dimensional spaces and H(div) conformal elements on general polytopes
Rémi Abgrall, Élise Le Mélédo, Philipp Öffner
We present a class of discretisation spaces and H(div)-conformal elements that can be built on any polytope. Bridging the flexibility of the Virtual Element spaces towards the elem…
