Finite Volume methods are the standard numerical methods for the solution of conservation laws, which represent fundamental laws of physics. Of particular importance is the use of the latter to model fluid flows in the form of parabolic and hyperbolic partial differential equations.

The course explains basic pitfalls of numerical methods for these equations and how to arrive at stable and convergent finite volume methods of first order.
The course is necessary for further studies within numerical analysis and also useful for students within applied disciplins where conservation laws are used.
