Learning Outcomes

Learning outcomes

Upon successful completion of this course, students will be able to: apply advanced numerical analysis techniques to prove error estimates for numerical approximations of elliptic and parabolic problems. demonstrate independence in the use of research materials to prove key results. write FEM code in FEniCS or Octave and construct appropriate numerical experiments to verify theoretical results. evaluate the correctness of numerical results by comparing them with both the theory of numerical methods and the theory of continuous problems.

General Competences

Search for, analysis and synthesis of data and information, with the use of the necessary technology. Adapting to new situations. Working independently. Decision-making. Production of free, creative, and inductive thinking. Promotion of analytical and synthetic thinking. Working in an interdisciplinary environment.

Syllabus

• Hilbert spaces, Riesz’s representation theorem, Lax-Milgram’s theorem, Cea’s theorem.
• Sobolev spaces, weak derivatives, Poincare-Friedrichs inequalities.
• Weak formulation and the Finite Element Method (FEM) for elliptic boundary value problems in 1D and 2D. A priori and a posteriori error estimates, adaptivity.
• Semi-discrete and fully-discrete schemes for parabolic equations. Temporal discretization with the Explicit and Implicit Euler methods, and the Crank-Nicolson method.
• Computer implementation of FEMs.

Teaching and Learning Methods - Evaluation
