Applied Numerical Field Computations


Finite element methods are standard tools for the solution of partial differential equations, for instance, Maxwell’s equations. They enable deep insight into a physical problem and therefore support knowledge gain similar to analytical methods or experiments.

Here, the established finite element method (FEM) is applied to the solution of multiphysics field problems. This includes a sound discussion of solution methods for time-dependent field problems, non-linear equation systems, as well as a mathematical description of multiphysics field problems, for instance, electro-thermal problems.

Lecture with exercise

The lecture with exercise is given by Dr. Buchau, who has more than 20 years of scientific experience in finite element methods. The format of this lecture with exercise is flipped classroom. Lectures and tutorials are recorded in advance and uploaded in ILIAS for self-study. In the lecture part, the theoretical background of numerical methods is presented and discussed. Of course, the focus is on the application of numerical methods to the solution of field problems as they are relevant in everyday engineering. Therefore, a lot of examples using the commercial software COMSOL Multiphysics are studied along with the fundamentals of underlying numerical methods and numerical formulations. At the listed times in C@mpus, the online materials are discussed in detail and students’ questions arising during self-study will be answered.

The exercise part is at the computer using COMSOL Multiphysics and MATLAB. Individual accounts to our servers are created to enable access to these simulation tools for the exercises in the lab and self-study. Hence, students learn to apply numerical field computations as an important engineering tool and see immediately the properties of numerical methods. The exercises will take place in our computer lab and students can discuss their models and solutions in small groups and with their lecturer.

Finally, the discussion of real problems with other students or the lecturer helps to understand the theoretical background and prepares for future work at an institute or in industry.

Please, check the room of the lecture and the exercise in C@mpus. Lectures will take place in the institute’s seminar room and exercises in the computer lab. The room for the next meeting is announced in the lectures and exercises, too.
