Electrostaticslates a charged sphere in a dielectric medium. The influence of initial values and relaxation parameter can be studied. A second example uses the boundary element method to solve the Poisson equation for a charge inside a spherical cavity.

Wavesed wave equation and discuss their stability properties. In a further computer experiment we study reflection at a closed or open boundary or at the border between two media with different refractive indices. We observe the effect of dispersion for pulses with different shape and duration.

https://doi.org/10.1007/978-3-7908-1954-0special iterative methods. We discuss the Jacobi and Gauss–Seidel methods and convergence acceleration by the method of successive overrelaxation. Another very efficient method for large systems is the conjugate gradients method which minimizes the gradient of a related quadratic form.
