The aim of the course is to provide the basis for the comprehension of the methods and procedures the finite element method and the multi body analysis are based on. The basic knowledge acquired during the course will give the student the possibility to explore the possible applications of the methods to solve engineering problems with particular attention to the structural field.
Automotive engineer has to own strong transversal knowledge covering the different area of a vehicle development. To this aim, some fundamental skills have to be present in the background of an automotive engineer.
Nowadays, the numerical modelling techniques are widely used in many engineering fields, consequently, they are considered a fundamental instrument for an engineer.
In this frame, the aim of the course is to provide the basis for the comprehension of the methods and procedures the finite element method and the multi body analysis are based on. The course will give to the student the basic knowledge for the applications of these methods to engineering problems with particular attention to the structural field.
Alongside the theoretical insights, space is dedicated to the practical use of the simulation techniques. In this way, the student can concretize the theoretical concepts. Moreover, the practical activities are aimed at stimulating the student’s critical thinking and autonomy of judgment increasing the development of problem solving attitude.
Students attending the course will learn about the wide capabilities of the numerical methods in the virtual simulation of the behaviour of structures and automotive systems. On successfully completing this course unit, students will be able to solve structural (static and dynamic) problems of simple complexity by using commercial codes widely present in industries. For example, they will be able to:
- prepare the numerical models of simple structures and multi body systems
- set up the boundary conditions for static and quasi-static analyses
- critically analyse the results of a virtual simulation and verify their reliability
The student attending the course will learn about the wide capabilities of the numerical methods applied in the virtual simulation to study the behaviour of structures with particular reference to the automotive sector. On successfully completing this course unit, student will be able to face structural problems of simple complexity applying the matrix calculus, the Finite Element Method (FEM) and the Multi Body (MBD) approach and by using commercial codes widely used in industries. Consequently, the student will be able to develop a numerical model of a simple real structural problem (with FEM and/or MBD).
In particular, for the part A of the course, the student will have to be able to:
- evaluate the stress and displacements field of a simplified structure applying the matrix calculus
- know the main types of finite element understanding their differences in terms of description capability
- understand the strategies for the application of the FEM theory to codes
- improve the accuracy of the results of a numerical model
- apply the acquired knowledge about the element type defining the most convenient type of discretization of a real problem and the most convenient boundary conditions to simulate the reality
- apply the critical thinking and the autonomy of judgment to analyse the results of a numerical simulation evaluating their reliability and defining possible strategies to improve their accuracy
Students attending the course must have the basic knowledge of geometry and numerical calculation. Moreover, they should be able to:

*The hours indicated for each topic are to be considered purely indicative and may change based on the progress of the lectures and the interest shown by students about the various topics.
The course is organized in frontal lectures, classroom practices and laboratory practices.
The frontal lectures concern the theory part of the course syllabus.
The classroom practices concern the execution of exercises on the matrix calculus. These exercises are preparatory for a part of the exam.
The laboratory practices concern the use of a widely used software for FEM pre- and post-processing phases (mesh generation, data pre-processing, problem solution, post-processing). During the laboratory practices the Finite Element Method is used to analyse simple structures in linear elastic hypothesis and considering static loading conditions.
All the parts in which the course is structured can be followed without significant differences in presence or remotely.
The part A of the course is organized in frontal lectures (22h), classroom practices (6h) and laboratory practices (12h).
In the frontal lectures the theoretical aspects of the topics listed in the course syllabus are developed.
In the classroom practices the theory of the matrix calculus is applied to study the stress and the displacements field of simplified structures. The exercises performed in these hours are preparatory for a part of the exam.
In the laboratory practices the knowledges developed in the frontal lectures are applied to study real simplified structural problems, using a widely used software for FEM pre- and post-processing phases (mesh generation, data pre-processing, problem solution, post-processing). In these hours, the FEM is used to analyse simple structures in linear elastic hypothesis. In order to improve the critical thinking and the autonomy of judgment of the student, he/she have to prepare a technical presentation where the activities carried out in the laboratory practices are described and the results obtained independently are critically discussed.

Assessment and grading criteria for blended exam (online and onsite)
To verify the expected learning outcomes, the exam of the Numerical Modelling and Simulation course is made up of:
- A written exam
- 2 laboratory reports
- An optional oral exam (only on student’s request)
Written exam:
The written exam is divided in two separate parts (part A and part B).
For what concerns the part A of the course, the written exam is aimed to verify:
- the capability to solve simple structural problems by matrix calculus
- the knowledges about the theory of the finite element method
- the knowledges about the commercial codes used for the finite element analysis carried out during the laboratory practice
To this aim, the written exam of the part A is made up of:
- one exercise about the solution of simple structural problems by matrix calculus
- two open questions about the theory of the finite element method
- one or two short answer questions about the use of commercial codes used for the finite element analysis carried out during the laboratory practice
For what concerns the part B of the course, the written exam is aimed to verify:
- the capability to solve problems of positioning, kinematic and dynamic of rigid bodies by matrix calculus
- the knowledges about the kinematics and dynamic of a multi body system with open chain
- the knowledges about the computing procedure in multi body dynamics
To this aim, the written exam of the part B can be made up of:
- one or two exercises with matrix calculus to solve positioning, kinematic and dynamic problems
- one or two questions about the theory of the multi body dynamics
- The two parts of the written exam will be carried out separately
- The duration of each part of the written exam is 1.5 hours
- The maximum score of each part is 14/30. The total score of the written exam is made up of the sum of the score of the two parts. Therefore, the maximum score of the written exam is 28/30
- The written exam will be carried out:

- The student can verify his written exam and any errors in a virtual classroom fixed by the teaching staff. The schedule of the virtual classroom will be communicated when the results of the exam will be available
For what concerns the part B of the written exam:
- During the exam, the student cannot leave the desk and the workstation, moreover he has to be always clearly visible by the webcam.
- The webcam has to capture the desk where the student will take the exam and the student himself.
- In the written exam it is forbidden the use of books or any type of notes. If necessary, a formulary will be provided by the teaching staff in the text of the questions.
- You can use a pocket calculator that cannot be connected to internet.
- Your smartphone has to switched on (it will be necessary at the end of the test), muted, and its screen has to be oriented toward the surface of the table.
- For each question it is required to do one picture of the written answer by the webcam. It is possible to add more pictures for each question. Each picture can be repeated more time before to select it. During the exam are no allowed attached files.
- For an acceptable quality of the picture the sheet must be approached to the camera. Sheets of size A5 are preferable for this operation (A5 is half sheet A4).
- Just after the conclusion of the exam it is required to upload ONE (only one) pdf file for the whole solution (your written sheets) on "Elaborati" section of Portale della Didattica. Number each written sheet before to take the photo of the written sheets with your smartphone.
- The additional file will be useful in case of no good resolution of the pictures during the test with Respondus platform. Only the solution visible in the picture will be considered for the verification of the solution on the additional pdf file. Format different than pdf type or multiple files will be not considered.
Onsite exam
For both the part A and B of the written exam:
- It is forbidden the use of books or any type of notes. If necessary, a formulary will be provided by the teaching staff
- During the exam it is strictly forbidden to use any web connection, therefore no electronic devices (computers or calculators with connection devices of any kind, mobile phones, smartphones, smartwatches, etc.) of any kind are allowed for any data retrieval or for any communication purpose during the exam
- It is allowed the use of a calculator (that cannot be connected to internet). The use of any other type of electronic device is strictly forbidden worth the cancellation of the exam

- It is strictly forbidden to speak with other people inside or outside the classroom in any way and for any reason
Laboratory reports:
The aim of the laboratory reports is to verify the knowledges about the use of the commercial codes used for the laboratory practices. The two reports concern, separately, the two parts of the course. In the laboratory reports the students have to show the procedures followed to perform the numerical analysis and the obtained results. The results have to be critically commented and discussed by the students. The requested reports consist:
- For the part A, in a short technical presentation. The report has to be made in .pptx format (or similar) and it must be submitted in .pdf format
- For the part B, the report can be made in .docx format (or similar) and it must submitted in .pdf format
- The maximum score of each report is 2/30
- The laboratory reports must be submitted within a defined deadline
- The laboratory report must be submitted with upload operation on the course webpage (“Portale della Didattica”)
- The deadline for the upload of the laboratory reports is mandatory: laboratory reports uploaded after the deadline will not be taken into consideration for any reason
- The deadline for the laboratory reports will be communicated through the webpage of the course (“Portale della Didattica”)
- If even just one of the two laboratory reports will be missing, the maximum score of the written exam will be automatically reduced to 24/30
- The laboratory reports can be done by teams of students: the teams must have a maximum number of students equal to 3
- A single upload has to be made for each student’s team. On the technical report the members of the student’s team have to be clearly indicated
Optional oral exam:
The optional oral exam has the same targets of the written exam. It consists in 2÷4 questions on the contents of the complete course (theory, classroom practice, laboratory practice of both part A and part B)
- The optional oral exam must be attended at the same date of the exam registration of the written exam
- The optional oral exam can be carried out only by students having a minimum score on the written exam (score of the part A + score of the part B) + the score of the laboratory report of 18/30
- The optional oral exam is evaluated with a maximum score of 30/30
- The optional oral exam will be carried out
- via PC using a video communication system. The general procedure for oral examination is provided by the Politecnico di Torino. More details will be provided during the course by the teaching staff for students which will attend the exam online
- in classroom with traditional execution, for students which will attend the exam onsite
General rules:
- The maximum score of each part is 14/30. The total score of the written exam is made up of the sum of the score of the two parts. Therefore, the maximum score of the written exam is 28/30
- The final score of the exam is given by the sum between the score of the written exam (the score of the part A plus the score of the part B) plus the score for the laboratory reports
- If the student decides to attend the optional oral exam, the final score of the exam is given by the mean score between:
- the written exam (score of the part A + score of the part B) + the score for the laboratory reports
- the optional oral exam (if applicable)
- The minimum score to pass the exam is 18/30
- A score larger than 30/30 will be registered as 30/30 with laude
- Only the total score of the written exam (score of the part A + score of the part B) can be rejected whereas the score of the written exam of a single part cannot be rejected. The score of the written exam can be rejected at every exam. If the student decides to attend the optional oral exam, the final score of the exam cannot be rejected.
- Students must verify that they are properly enrolled in the exam. Only student regularly enrolled can carried out the exam
- The students which will held the exam online must check, well in advance, that they are equipped with the adequate means to take the exam according to the exam procedure proposed by the teaching staff (personal computer equipped with webcam or tablet, browser, network connection suitable for videoconferencing).
