Prof. Dr. Bangerth - Using Finite Elements via the Deal.II Library
Texas A&M University
Modern finite element codes are far more complex than what can be written from scratch within any reasonable amount of time: they utilize adaptive meshes for complex geometries, multigrid methods, sophisticated solvers and preconditioners, and need to run on hundreds, thousands, or even more processors. Software of this kind can only be written by reusing libraries that provide this functionality in a generic way. This course will examine the typical structure of finite element codes. It will then demonstrate the use of the open source deal.II library (see http://www.dealii.org) that is widely as the basis for finite element programs in research and provide an overview of its features.
