Summary

The aim of the course is to give a theoretical and practical knowledge of the finite element method for saddle point problems, such as fluid dynamics, elasticity and electromagnetic problems.

Content

Keywords

Partial differential equations,  saddle point problems, finite element method, Galerkin approximation, stability and convergence analysis.
