Introduction to the Finite Element Method

Detailes on our lecture "Introduction to the Finite Element Method"


  • Fundamental concepts of discretization and approximation
  • Mathematical modelling with partial differential equations
  • Strong and weak forms of PDEs (variational principle, principle of virtual work, Ritz & Galerkin methods, method of weighted residuals)
  • Isoparametric element formulations for linear continuum elements in heat transfer and structural mechanics
  • Numerical integration and solution of sparse systems linear of equations
  • Enforcement of boundary conditions
  • Mathematical foundations of FEM and convergence analysis (h- & p-refinement, error estimation and adaptivity)
  • Locking phenomena, mixed methods and reduced integration
  • Modal analysis and time-integration methods for dynamics
  • Structural beam and truss elements

Digital teaching in winter term 2021-2022

The lecture is organized in a blended learning format. Learning units with videos, slides, tutorial and other materials are provided in the Moodle course. Additionally, there will be a weekly interactive lecture session on Tuesdays at 09:50 for reviews, group exercises and questions. Depending on the pandemic situation and rules, this session will be held in presence (in the lecture hall) or via Zoom.
