      For the shallow water equations, see for example the work of Xing & Shu (, ) and their well-balanced Weighted Essentially Non-Oscillatory (WENO) schemes for 1-D and 2-D Cartesian meshes for finite difference, finite volume and discontinuous Galerkin methods. These methods are semi-discrete, in which total variation diminishing (TVD Cited by: Hamilton–Jacobi (H–J) equations are frequently encountered in applications, e.g., in control theory and differential games. H–J equations are closely related to hyperbolic conservation laws—in one Cited by:

    BASIC APPROACH: Comprehensive -- this text explores the "full range" of finite element methods used in engineering practice for actual applications in computer-aided design. It provides not only an introduction to finite element methods and the commonality in the various techniques, but explores state-of-the-art methods as well -- with a focus on what are deemed to become "classical techniques 5/5(2). A non-oscillatory piecewise-quadratic reconstruction of pointvalues from their given cell averages; and #2. A central differencing based on staggered evolution of the reconstructed cell averages. This results in a thirdorder central scheme, an extension along the lines of the second-order central scheme of Nessyahu and Tadmor [NT].

    A higher-order space-time finite-element method for moving-body and fluid-structure interaction problems L. Diosady, S. Murman, C. Carton de Wiart Science and Technology Corporation, USA. Many of the recently developed high-resolution schemes for hyperbolic conservation laws are based on upwind differencing. The building block of these schemes is the averaging of an approximate Godunov solver; its time consuming part involves the field-by-field decomposition which is required in order to identify the “direction of the wind.
