Assessment and Grading

Assessment activities:

Description of the activity Assessment Activity % Remediable subject
Practical computer sessions Report including the description of the solution, analysis of the results and conclusions. It will be especially evaluated the correctness of the solution and the interpretation of the results and conclusions. 20 No
Practical exercises Report including the description of the solution, analysis of the results and conclusions. It will be especially evaluated the correctness of the solution and the interpretation of the results and conclusions. 40 No
Case studies Report including the description of the solution, analysis of the results and conclusions. It will be especially evaluated the correctness of the solution and the interpretation of the results and conclusions. 40 No

Grading

The final mark of the course will be determined through the evaluation of the reports of the exercises delivered during the course by the students according to:

FM = Final Mark
PE = Practical exercises
CS = Case studies
S = Simulations

FM= 0.4*PE + 0.3*CS + 0.3*S

For a given category (i.e. PE, CS and S), the student will have to present individual, sometimes in group, original reports or Finite Element models covering all the contents of the course. The mark for each category (PE, CS and S) is the mean of the individual reports’ marks.

All students' reports and FE models will be corrected and evaluated and returned to the students to improve the assimilation of the different concepts of the course. The students will not have the opportunity to resubmit exercises that have been marked as not correct.

Plagiarism will be especially prosecuted. Students submitting not original reports of FE models will receive a 0 as global mark for the course.

Specific criteria for the "No show" grade:
Only those students that do not deliver any of the suggested exercises will receive a Not Presented (NP) mark

Single Assessment:
The student will be asked to prepare a project report on the design of a composite part using the Finite Element Method.

Minimum requirements to pass:
The minimum mark to pass the course is 5.0 over 10

Mentorship

Students can arrange individual or group tutorships, mainly on-site but on-line will be also possible. There is a special forum in the webpage of the course for posting doubts and questions so solutions will be shared with everyone. E-mail can be also used to solve questions or doubts and set tutorship appointments.

Communication and interaction with students

Communication with students will be via the News forum of the course’s Moodle and also by e-mail.
