Based on the L^2 conservation law of KdV equations, we adopt the conservative and dissipative numerical fluxes for the nonlinear convection and linear dispersive terms, …
WebArbitrary Lagrangian-Eulerian Formulation (ALE) The partial differential equations of physics are usually formulated either in a spatial coordinate system, with coordinate axes fixed in space, or in a material coordinate system, fixed to the material in its reference configuration and following the material as it deforms. WebFor the finite element method, such as for the arbitrary Lagrangian Eulerian formulation, the problem requires a complicated interpolation function momentum equation and the incompressibility constraint (shape function) on the local grid lines which results in of the Navier–Stokes problem are analyzed using a proce- the regional loss of accuracy in the …
