The provided code is clear but slow (explicit time-stepping, dense loops). Hesthaven warns about this, but novices may mistakenly copy the style into production code.
4.5/5 Recommended companion: Riemann Solvers and Numerical Methods for Fluid Dynamics (Toro) + Finite Volume Methods for Hyperbolic Problems (LeVeque). The provided code is clear but slow (explicit
The chapter on limiting for high-order methods is worth the price alone. Hesthaven clearly explains why standard TVD limiters destroy accuracy at smooth extrema and how to implement more sophisticated approaches (moment limiters, WENO-type limiting for DG). The chapter on limiting for high-order methods is
The analysis and algorithms are mostly presented in 1D, with a final chapter extending to 2D on structured grids. There is little on unstructured meshes, mesh adaptation, or parallel (MPI/GPU) implementation—which is where real conservation law codes live today. There is little on unstructured meshes, mesh adaptation,
