High order finite volume method

WebIn this work we propose a novel strategy to define high-order fully well-balanced Lagrange-projection finite volume solvers for balance laws. In particular, we focus on the 1D shallow water system as it is a reference system of balance laws with non-trivial stationary solutions. Nevertheless, the strategy proposed here could be extended to other interesting … WebThis method of deriving the discrete equation using Taylor’s series expansions is called the finite-difference method.
