052497 - NUMERICAL ANALYSIS FOR PARTIAL DIFFERENTIAL EQUATIONS

Obiettivi dell'insegnamento

MAIN OBJECTIVES

The aim of this course is twofold: on the one hand, to systematically address multi-dimensional finite element analysis for partial differential equations (PDEs), with increased attention to applications in Science and Engineering; on the other hand, to sustain the theoretical analysis with laboratory sessions. Extensive hands-on sessions on projects of engineering relevance are planned

COMPLEMENTARY OBJECTIVES

The complementary aim of the course is to train students: to use a widely-spread programming language as Matlab for algorithm development and numerical computations; to be able to utilize advanced simulation methods for the numerical approximations of PDE models.

Blended learning andflipped class innovative teaching methods will be exploited to allow students to acquire a good level of autonomy in learning new topics and to improve specific communication and soft skills like problem-solving and teamworking.

Risultati di apprendimento attesi

Lectures and computer labs will allow students to:

- develop a broad and deep knowledge of numerical methods for Partial Differential Equations;

- understanding and mastering the theoretical properties of numerical methods and algorithms for solving various mathematical problems arising in Science and Engineering;

- critically apply advanced numerical models to mathematical problems stemming from real-world engineering applications independently of their own field of specialization;

- motivate the choice of the adopted methods and tools;

- critical interpretation of the results obtained in the light of the theory through the implementation of the algorithms using the Matlab software;

Practical projects will allow students to:

- improve higher-order thinking skills (critical thinking, problem-solving, communicative and working group skills);

- analyze critically the obtained numerical results;

- summarize and present the results achieved during the analysis and implementation activities;

- write a scientific document.

Labs and exercise sessions. Most of the methods presented during the lectures will be numerically investigated during the laboratory sessions based on employing the software Matlab.

Project. The project is an integral part of the course. The projects deal with an applicative or advanced theoretical problem, not necessarily dealt with during the course. The goal is to help students developing high-order thinking skills such as critical thinking, problem-solving attitude, communicative and working group skills. Projects will be assigned during the semester. Their evaluation will be based on the produced scientific documentation and numerical code, as well as on an oral presentation.

Prerequisiti

Some introductory level courses of Numerical Analysis, Partial Differential Equations, Functional Analysis, or equivalent, and some programming experience.

Modalità di valutazione

The exam consists of a written test and of a project

Written test. The written exam takes place in the computer room. The exam covers all the theoretical and practical arguments considered at the lectures and lab sessions. Part of the questions and problems are solved numerically with MATLAB; the exam includes the implementation and programming of numerical algorithms. The problems mainly focus on definition, application of important lemmas and theorems, and important examples. Light calculations may be needed. It is not allowed to use any form of course material. The questions will be answered without books, notes, preparations, etc.

Course project. Students are required to complete a project of their own. Each student works on an applicative or advanced theoretical problem, not necessarily dealt with during the course. The project must focus on theoretical and computational aspects. The assessment of the project will be based on subject knowledge matters, oral delivery, quality of the work, demonstration of team work and individual contributions. Project presentations last 20 minutes plus 10 minutes for questions.

Intended learning outcomes. Students are expected to

- know and understand numerical methods for differential problems, as well as evaluate their properties;

- write and interpret algorithms;

- choose the most appropriate numerical scheme for solving a given differential problem;

- solve mathematical problems with the computer via MATLAB;

- implement algorithms and use them appropriately;

- critically reason and interpret the results obtained in the light of the theory;

- model and numerically simulate Engineering problems.
