How to Use NDSolve for Wave Pulse Propagation?

[FunkyDwarf]

Hey guys,

I'm sure I'm doing something really daft in not getting this to work, but...

I want to use NDSolve to numerically solve the time evolution of a (one-dimensional) wave pulse in either the time dependent Schrödinger or KG equations. My inability to do so stems from my lack of understanding of what boundary/initial conditions NDSolve wants/needs.

Essentially i'd like to just specify the initial form (gaussian or whatever) and a velocity and watch the thing fly off into the sunset, under what conditions will this occur?

Cheers

Dear, i think you have to read few pages from the following book,

"Differential equations with Mathematica" by Martha L. Abell and James P. Braselton.
there is a separate topic with deal with the wave equaiton
you can find it on gigapedia
