Written exam (multiple choice, open questions)
Description of the modifications to the Q3 2019-2020 online assessment procedures (Covid-19)
The exam will take place over half a day during the session. The exam will take place using an online assessment platform according to the schedule defined by the faculty. The exam is performed with open course notes (syllabus, notes, slides, etc.). It will successively include an exercise and then an open question: - The exercise will be an exercise consisting of the analysis of the truncation error, the consistency and the stability of a numerical scheme. The question will be presented in a form similar to that of exercises of this type given and resolved during exercise and practical sessions. - The open question will be essentially based on the understanding of the subject and on the student's ability to provide a substantiated critical answer (advantages, disadvantages, potential, limitations, properties, behavior, cost, efficiency ...) on aspects of numerical techniques applied in Computational Fluid Dynamics. Serious preparation is therefore necessary, and the notes are there to draw certain relationships and concepts, to support certain reasoning, certain criticisms and/or guide the reflections and/or opinions given in the response. They are not intended to simply restitute the matter as it is. The overall weighting is as follows: - 25% for the exercise - 75% for the open question The examination will successively include: 1) The supply of the exercise. The student must then, within a limited time, prepare his answer on paper in the form of a written note in a strictly handwritten manner. A canvas will be imposed, and each page must be numbered with a unique and consecutive number starting at 1. At the end of the allotted time, the student will transmit electronically a scan/photo form all of their handwritten note. The time allotted will be 1 hour: 50 minutes of reading/preparing/writing the response + 8 minutes for the electronic transmission of the scan/photo of the handwritten response note + 2 minutes of beat. 2) Then the student will receive the open question. The student must then, within a limited time, prepare his answer on paper in the form of a note written in a strictly handwritten manner. A canvas will be imposed, and each page must be numbered with a unique and consecutive number starting at 1. At the end of the allotted time, the student will transmit electronically a scan/photo form all of their handwritten note. The time allotted will be 1 hour and 20 minutes: 1 hour and 10 minutes of reading/preparing/writing the response + 8 minutes for the electronic transmission of the scan/photo of the handwritten response note + 2 minutes of beat. The overall time allocated for each student will be 2 hours and 20 minutes. A procedure for verifying that questions and answers have been received correctly will be set. This procedure will include a verification and an approval of the quality and the readability of the questions and the scan/photo of the answers. Thereafter, a procedure will be provided for a brief exchange with the student in order to validate the technical conditions under which the examination was carried out.
