### Learning Objectives

The objective is to provide a general introduction to numerical simulation techniques, demonstrating their application in different fields, by means of writing software code in Python to solve specific problems.
The student will acquire a basic knowledge of simulation methodologies and of the techniques for assessing the validity of simulation results.

### Program

1. Course introduction
1.1 The Python language: a crash introduction

2. Ordinary differential equations
2.1 A case study: the "phogoid" motion of aeromobiles

2.3 A more complete method, and orders of convergence
2.4 Higher order schemes, and Runge-Kutta methods

3. Partial differential equations: convective problems
3.1 The convective motion in 1D
3.2 Numerical stability and CFL condition
3.3 The diffusion equation in 1D
3.4 Convection and diffusion together: the Burgers equation

7.3 Gauss-Seidel and Successive Over-Relaxation methods
7.5 Multigrid methods

8 Simulations based on emerging dynamics
8.1 Cellular automata
8.2 Lattice gas cellular automata
8.3 Lattice Boltzmann methods

### Bridging Courses

The students should have acquired already competences in analysis, discrete mathematics, probability and statistics.
They should be also capable of writing pseudo-code, by having acquired already basic programming competences.

### Learning Achievements (Dublin Descriptors)

Knowledge and understanding: the student will know the main simulation methodologies in a broad range of application contexts.
Applying knowledge and understanding: the student will be capable of identifying the simulation methodology most appropriate to a specific real problem, and will be able to write the code or pseudo-code of a simulation program.
Making judgements: the student will be able to evaluate autonomously if a simulation output is reasonable, and to establish procedures for verifying its correctness.
Communication skills: the student will acquire a scientific language appropriate in the field of numerical simulation.
Learning skills: the student will be able to study in deeper depth specific topics, not discussed during the course, using scientific textbooks also at a specialistic level.

### Teaching Material

The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it

### Supporting Activities

Slides of the course lessons, example Python code.

### Teaching, Attendance, Course Books and Assessment

Teaching

Frontal lessons and laboratory activities.
Realization of simulation projects and evaluation, on Moodle.

Course books

The study material and the relevant bibliography will be provided by means of the Moodle platform.

Assessment

Realization of a simulation project agreed with the teacher, defined by means of a set of requirements.
The project should be realized and submitted for evaluation within two weeks (ten working days) at most.
The evaluation criteria are: the number of requirements met, the quality of the implemetation (including documentation), the correctness of the assessment of the simulation results.
Each criterion is graded on a scale including insufficient, fair, good, excellent.
Subsequent oral exam, based on the discussion of the project and aimed at sampling the student's competence on the other aspects of the course programme, graded on the same levels.

Disability and Specific Learning Disorders (SLD)

Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.

To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.

### Additional Information for Non-Attending Students

Teaching

The same as for attending students, thanks to the availability of course material through the Moodle platform.
