Hard Guarantees at a Measured Price: Entropy-Stable Learned Finite Volumes for Compressible Flow
Learned solvers for compressible flow are usually compared to classical methods at equal mesh resolution rather than at equal computational cost, and they typically offer no guarantee that their solutions remain physically admissible. We present a learned finite volume scheme for…
