Description

Once a method has been programmed in Mathematica, it is straightforward to provide instructive visualizations. Three examples are provided here:

1. A solution of the nonlinear kdV equation (using the Galerkin method) that exhibits the breakup of a smooth initial condition into solitons. 2. A solution to the linear wave equation with varying wave speed and an oscillating boundary (using the CTCS grid) 3. A gravitational collapse from a random initial condition via the particle in cell method.

More methodologies are available in the book.
