The discussion is placed in a physical context, i. e. computational problems are motivated from basic physical considerations. Presenting selected examples for solutions to these problems, I introduce the basic ideas of the most commonly used numerical methods.18 pages, 7 figures; proceedings contribution to "Structure formation in the Universe: Chamonix 2007"Astrophysicstext
