Solver::Local::Riemann::Roe
===========================

:bdg-link-secondary-line:`src/Solver/Local/Riemann/Roe.H <../../../../doxygen/Roe_8H_source.html>`

This implements the Riemann Roe solver.

Notation and algorithm follow the presentation in Section 5.3.3
of *Computational Gasdynamics* by Culbert B. Laney (page 88)

This solver uses an optional entropy fix
  Option 1: chimeracfd method https://chimeracfd.com/programming/gryphon/fluxroe.html
  Option 2: Eq. 4.3.67 in *Computational Fluid Dynamics for Engineers and Scientists* by Sreenivas Jayanti
