Methods on unstructured grids, WENO and ENO Recovery techniques

摘要: Finite volume approximations comprise the most successful class of discretisation techniques for conservation laws compressible fluid mechanics. Their success is based not only on their relative simplicity as compared to finite difference and element approximations, but also flexibility ability unite ideas from elements with those differences. A first basic approximation Euler equations can be written down arbitrary grids directly itself coded by a novice student within short amount time.
