For example, the Lax-Wendroff finite-difference scheme for 1-D transport equations was derived by constructing a quadratic Lagrange interpolating polynomial. Mathematica solved a linear system to obtain the polynomial coefficients; then, replacement rules were used to substitute these coefficients into the property for sale moniaive scotland

WebThe Lax-Wendroff scheme for the advection equation may be written in the form of (8.60) by defining the Lax-Wendroff Flux F L W as: (8.64) F L W ( j − 1 / 2) = F L W ( u j − 1, u j) = a u j − 1 + 1 2 a ( 1 − Δ t Δ x a) [ u j − u j − 1] (8.65) F L W ( j + 1 / 2) = F L W ( u j, u j + 1) = a u j + 1 2 a ( 1 − Δ t Δ x a) [ u j + 1 − u j] WebWe continue with our discussions on the damping and dispersion of the upwind scheme, and also derive the Lax Wendroff scheme.
