Aim
The aim of the course is to teach computational methods for solving ordinary and partial differential equations. This includes the construction, application and analysis of basic computational algorithms. Problem solving by computers is a central part of the course.

Knowledge and understanding
For a passing grade the student must

be able to discretize ordinary and partial differential equations. Moreover, students have to independently implement and to apply such algorithms.

Skills and abilities
For a passing grade the student must

- be able to independently select and apply computational algorithms.

- be able to evaluate both accuracy and relevance of numerical results.

- report solutions to problems and numerical results in written form.

Judgement and approach
For a passing grade the student must

- write a logically well structured report in suitable terminology on the construction of basic mathematical models and algorithms.

- write an algorithmically well structured report in suitable terminology on the numerical solution of a mathematical problem.
