Guarantees by Construction for Learned Finite Volume Schemes on Steady Supersonic Flow
Denis Gueyffier
A second order finite volume scheme rests on two local quantities: a gradient reconstructed in each cell, and a limiter which scales it down where the reconstruction would overshoo…

Solver Exactness, Learned Flexibility: Equivariant Boundary-Correction Operators for Stokes Flow
Denis Gueyffier
Computing the viscous Stokes flow around a shape requires solving a boundary-integral equation, and for a new shape the solve must begin from scratch. Learned operators promise to…
