Web1D linear advection equation (so called wave equation) is one of the simplest equations in mathematics. The equation is described as: (1) ¶ ∂ u ∂ t + c ∂ u ∂ x = 0 where u ( x, t), x ∈ R is a scalar (wave), advected by a nonezero constant c during time t. The sign of c characterise the direction of wave propagation. WebThree numerical methods have been used to solve the one-dimensional advection-diffusion This partial differential equation is dissipative but not dispersive. We consider the Lax-Wendroff scheme which is explicit, the Crank-Nicolson scheme which is implicit, and a nonstandard finite difference scheme (Mickens 1991).
