FEM

Finite elements : Theory and Algorithms : DS 291 (Aug) 3:1

This course will provide an introduction to the finite element methods and their applications to the scalar convection diffusion equations and to the Navier-Stokes equations. The course will cover the basic mathematical theory of the finite element methods, and the development of fully practical finite element algorithms for solving partial differential equations elliptic and parabolic scalar PDES, linear elasticity, Mindlin-Reissner plate problem, Navier-Stokes equations. Further, the lab component will consists of programming assignments including the implementation of the finite element algorithms, solving scalar and Navier-Stokes equations using the in-house package ParMooN

Topics:

Generalized (weak) derivatives, Sobolev norms and associated spaces, inner-product spaces, Hilbert spaces, construction of finite element spaces, mapped finite elements, two- and three-dimensional finite elements, Interpolation and discretization error, variational formulation of second order elliptic boundary value problems, finite element algorithms and implementation for linear elasticity, Mindlin-Reissner plate problem, two-dimensional stationary incompressible Navier-Stokes equations systems in fluid mechanics.
