Steady Transport-Diffusion Equations,ferential operators in which the second-order terms are dominated by the first-order terms, giving rise to the boundary layer phenomenon. To better deal with these equations, a modified version of the Legendre collocation grid will be considered.Canvas 发表于 2025-3-23 20:27:32
The Spectral Element Method,e approximated solution is a patchwork of different algebraic polynomials defined in the subdomains and is determined as the result of a preconditioned iterative procedure. At any iteration, in any subdomain, the corresponding polynomial satisfies a collocation problem.的事物 发表于 2025-3-23 23:06:45

Time Discretization,We turn our attention to the approximation of partial differential equations where the solutions also depend on time. We discuss some well-known boundary-value problems and consider their discretization both in space and time.
