Encyclopedia > Numerical partial differential equations

Numerical partial differential equations is the branch of numerical analysis that studies the numerical solution of partial differential equations. Numerical analysis is the study of algorithms for the problems of continuous mathematics (as distinguished from discrete mathematics). ... In mathematics, and in particular analysis, a partial differential equation (PDE) is an equation involving partial derivatives of an unknown function. ...


An example of a technique in numerical PDEs is the finite element method. In numerical analysis, the finite element method (FEM) is used for solving partial differential equations (PDE) approximately. ...

Differential Equations (4849 words)
An Introduction to Partial Differential Equations with MATLAB by Matthew P. Coleman (Chapman and Hall/CRC) exposes the basic ideas critical to the study of PDEs-- characteristics, integral transforms, Green's functions, and, most importantly, Fourier series and related topics.
Finally, the dif­ferential equations course is one of the few undergraduate courses where it is possible to give students a glimpse of the nature of contemporary mathematical research.
We expect students to understand the meaning of the variables and parameters in a differential equation and to be able to interpret this meaning in terms of a particular model.
Numerical Analysis of Applied Partial Differential Equations (1809 words)
Numerical analysis is the mathematical method that uses numerical approximations to obtain numerical answers to the problem.
Numerical analysis also considers the accuracy of an approximation, and when the approximation is good enough.
where (2) is the forward difference equation, (3) is the backward difference equation, and (4) is the central difference.
