On the efficient implementation of PVM methods and simple Riemann solvers. Application to the Roe method for large hyperbolic systems
作者:
Highlights:
• An efficient implementation of PVM methods is proposed.
• The relation between the PVM methods and simple Riemann solvers is revisited.
• A new implementation of the Roe method is proposed, named as Newton Roe method.
• Newton Roe method is more efficient than the standard one for large hyperbolic systems.
• Numerical tests with the two-layer shallow-water system and the QBME model are shown.
