Participants:

This lecture is suitable for students in mathematics (Bachelor, Master, Diploma) and in mathematical physics with the standard knowledge from the introductory lectures and functional analysis as well as from basic computational partial differential equations (standard Galerkin FEM).

Content:

The standard (or conforming) Galerkin finite element methods (FEMs) are based on a space Vh that is a subset of the space, where the continouos problem is posed. In many contexts, e.g., a divergence-free condition of the solution, smooth test functions, meshes with different shapes, or ansatz functions with variable polynomial degrees, those methods become complicated. To break with the conformity relation can lead to easier methods. However, this leads to additional consistency or nonconformity errors in the error analysis. The lecture will introduce several non-standard FEMs, in particular non-conforming and discontinuous Galerkin FEMs. The a priori and a posteriori error analysis of the methods, as well as their implementations and relations between different FEMs are discussed.
