Numerical methods • Most PDEs cannot be solved analytically. • Variable separation works only for some simple cases and in particular usually not for inhomogenous and/or nonlinear PDEs. • Numerical methods require that the PDE become discretized on a grid. • Finite difference methods are popular/ most commonly used in science. They replace

One says that a function u(x, y, z) of three variables is "harmonic" or "a solution of the Laplace equation" if it satisfies the condition The nature of this failure can be seen more concretely in the case of the following PDE: for a function v(x, y) of two variables, consider the equation The nature of this choice varies from PDE to PDE. To understand it for any given equation, existe…

Numerical Methods for Partial Differential Equations is a bimonthly peer-reviewed scientific journal covering the development and analysis of new methods for the numerical solution of partial differential equations. It was established in 1985 and is published by John Wiley & Sons. The editors-in-chief are George F. Pinder (University of Vermont) and John R. Whiteman (Brunel University).

The numerical approximation of partial differential equations is an important ... Typically a PDE in itself has infinitely many solutions.

ing issues of numerical methods in a synergistic fashion. So the first goal of this lecture note is to provide students a convenient textbook that addresses both physical and mathematical aspects of numerical methods for partial dif-ferential equations (PDEs). In solving PDEs numerically, the following are essential to consider:

Numerical methods for PDE (two quick examples) Discretization: From ODE to PDE For an ODE for u(x) defined on the interval, x ∈ [a, b], and consider a uniform grid with ∆x = (b−a)/N, discretization of x, u, and the derivative(s) of u leads to N equations for ui, i = 0, 1, 2, ..., N, where ui ≡ u(i∆x) and xi ≡ i∆x.
