Content

The topic of the course is to provide knowledge in numerically solving elliptic boundary value problems using the finite element method. We first present some basics like the weak formulation of these boundary value problems.
Then we study the finite element approach, in its various aspects, such as grid generation, choice of ansatz spaces, data structures for implementation, numerical integration, error estimates, a posteriori error estimates and solution techniques for the resulting systems of equations. A finite element solver in Matlab is provided to also get some practical experience.
