Introduction This is a repository for information related to multigrid, multilevel, multiscale, aggregation, defect correction, and domain decomposition methods. These methods are used primarily by scientists and engineers to solve partial differential equations on serial or parallel computers. Multigrid has the property of using linear time and space to solve a collection of interesting ...

GetDP: a General Environment for the Treatment of Discrete Problems Patrick Dular and Christophe Geuzaine Version 0.85, 21 January 2002 Description GetDP is a scientific computation software for the numerical solution of integro-differential equations, using finite element and integral type methods. The main feature of GetDP is the closeness between the input data defining discrete problems ...

The Animated Telegraph Equation This demonstration illustrates the behaviour of solutions of the telegraph equation u_{tt} +(a+b)u_t+abu= c^2 u_{xx} u(0, t) = 0 u(l, t) = 0 u(x, 0) = f(x) u_t(x, 0) = g(x) In this example c=1, l=10, the intial amplitude consists of one bump centered on x=3. The initial speed is chosen to be g(x) = -cf'(x) - (a+b)f(x)/2, so that, when there is no dispersion the bump ...

Green's Functions Tutorial Introduction to Green's Functions The basic idea of a Green's function is very familiar to students of mathematical physics. However, most engineers are not typically exposed to the concept of a Green's function until possibly at the upper-graduate level. Green's functions play an important role in the solution of linear ordinary and partial differential equations, and ...

Back to Contents! Next: Force Revisited Up: CONSERVING EQUATIONS Previous: CONSERVING EQUATIONS Math Unit III: More on the derivative and differential equations In the last unit, we discussed how mathematicians and scientists deal with quantities that change in ways other than linearly. The key idea turns out to be the rate of change of the quantity. The lowbrow way to measure the rate of change ...
