Metodoloxías
Metodoloxías Descrición
Prácticas a través de TIC Methodology that allows students to learn effectively, through practical activities (calculations and simulations) the theory of fluid mechanics, through the use of information and Communication Technologies.
Traballos tutelados Methodology designed to promote the autonomous learning of students, with the tutoring of the teacher in class.
This teaching system is based on two basic elements: the independent learning of the students and the follow-up of this learning by the teacher-tutor.
In this sense, several exercises will be carried out throughout the course during and outside class hours to continuously monitor the students' learning process in the subject.
Presentación oral Presentation of the students to their peers of the results obtained in their individual tutored work. The presentation is followed by a Q&A session with the professor and the other students.
Proba mixta Final evaluation exam consisting in a written test in which it will be necessary to answer different types of theoretical questions as well as to solve problems.
Sesión maxistral Face-to-face activity in the classroom that serves to establish the fundamental concepts of the subject. It consists of oral presentation complemented with the use of audiovisual media and the introduction of some questions addressed to students, in order to transmit knowledge and facilitate learning.

Descrición
ICT exercices will consist in basic programming in Matlab, as well as a familiarization with the open source CFD OpenFoam code, including basic tutorials with mesh generation, solver parameterization, and post-processing of results. This activity will be carried out under the direction of the professor, who will solve all the difficulties that students face.

Tutored work will consist in programming basic finite volume methods in Matlab, and solving a case study with OpenFoam. It will start in the classroom with the support of the professor to solve a maximum of doubts and the student will finish it autonomously.

Observacións avaliación
The written exam will consist in a quizz followed by a several questions that need a higher level of reasoning and development. Failure to reach a minimum grade of 4/10 in the exam will impede success in this course.

Tutored works will be individual; there will one for the first part of the course (basics of finite volumes) and one for the second part (CFD simulation of a test case). It will be necessary to deliver the reports in time and form. In addition, it will require a public oral defense. The report and the presentation given as well as the answers to the professor's questions during the compulsory presentation will be taken into account for the evaluation of this activity. Failure to make the presentation will result in a grade of zero.



General evaluation criteria:

* Clarity, extent and quality of report.

* Clarity and quality of oral presentation of the work.

* Mastery of the topic and adequacy of the student's answers to the teacher's questions in the presentation session.

In this subject no academic dispensation is accepted.

The evaluation criteria of the second opportunity are the same as in the first.

If a student fails to pass the course at the first opportunity, at the second opportunity they will only be able to submit the review and improvement of those works and exercise delivered and previously qualified as unsuitable.
There will be a second opportunity for the exam.

General EMJMD Sustainable Ship and Shipping  SEAS 4.0 evaluation rules:

- Students will have only two oportunities to pass a course. If failing to do so, they may be forced to leave the degree.

- No part time or lecture attendance exemption are allowed in this degree.

Observacións

To help in achieving a sustainable environment and to get the objective of number 5 action of the "Ferrol Green Campus Action Plan" (Healthy and environmentaly and socially sustainable research and teaching):

The assignments to be done in this course:

- Will be required in digital format.

- Will be delivered using Moodle, with no need to print them.

In case it is necessary to print them:

- Plastics won´t be used.

- Two side printing will be used.

- Recycled paper will be used.

- Printing drafts will be avoided.

A sustainable use of the resources should be done, together with the prevention of negative impacts on the environment.
