Abstract

  • Many physical phenomena are modeled by partial differential equations (PDEs) that cannot be solved analytically anymore. Thus our aim is to compute a -hopefully- reliable approximation of the solution to such a PDE. One of the basic steps is to transfer the infinite-dimensional problem to something that computers -with finite memory- can handle. In this ’What is...’ talk, we will get an idea how the Galerkin Finite Element Method (FEM) serves this purpose. In the end, we shall also see a special variant, namely the Discontinuous Galerkin (DG) method, and discuss its uses.
