Avaluació i qualificació

Activitats d'avaluació:

Descripció de l'activitat Avaluació de l'activitat %
Test examination #1 There will be three individual written examinations along the course, which are given a total of 15% percentage mark. Each one of these exams consists of a short test of 5 questions (each one of the three tests is worth a 5% of the percentage mark). 5
Test examination #2 This is the second short test. 5
Test examination #3 This is the third (and last) short test. 5
Practical assignment Groups of two people shall be made. There will be one assignment per group, which is worth of 85% of the percentage mark. It consists of an essay as well as an oral presentation of a practical example that has to be solved with a commercial CFD package. From the 85% percentage mark assign to the practical essay, 15% shall correspond to the evaluation of the geometry generated for the practical study, 15% shall correspond to the evaluation of the generated mesh, 35% shall correspond to the written essay and 20% shall correspond to the oral presentation. Along the course there will be deadlines for evaluating the geometry and the mesh. The written essay and the oral presentation shall be presented at the end of the course. 65
Oral presentation of the practical assignment Oral presentation of the practical assignment. At the very same day, the written essay that should include all the findings of the practical assignment must be given to the teaching staff. 20

Qualificació

In order to pass the course, you must:

1. Have a 75% minimum attendance for both classroom and laboratory sessions.

2. Obtain a final grade equal or greater than 5, computed from:

Final Grade = 0,15 TG + 0,85 PG

where:

TG = averaged grade of the three examination tests carried out along the course.
PG = grade of the practical assignment.

The practical assignment consists of solving an Engineering problem with CFD and it is evaluated from:

PG = 0,20 geometry grade + 0,30 mesh grade + 0,20 oral presentation grade + 0,30 written essay grade.

Criteris específics de la nota «No Presentat»:
The mark NP (not present at the exam) will be assigned in case that the student:
1. Fails to attend a minimum of 75% for both classroom and laboratory sessions.

and/or

2. Does not give in the practical assignment at the expected date or before.


La nota NP (no presentat) s'aplicarà quan l'estudiant:

1. No atengui a un mínim del 75% de les sessions de laboratori i d'aula.

i/o

2. No entregui el treball pràctic en la data convinguda o abans.

Observacions

It is necessary to have some notions at a medium level on mathematics, physics and, particularly, fluid dynamics.
We strongly recommend to come with a USB flash drive in order to store all the information developed during the laboratory sessions.
