Knowledge and understanding: The student will be provided with the theoretical and practical notions to be able to independently design a 3D CAD model, obtain its properties, handle and modify it. He will also be able to export the model in different formats useful for analysis in other software. Finally, the student will be explained the meaning of discretization of a geometry and the different types of mesh will be illustrated.
Ability to apply knowledge and understanding: The student will be able to independently choose the best strategy for drawing the 3D model of the analyzed geometry. It will then be able to evaluate a possible discretization of the latter based on the analysis to be performed (FEM / CFD).
Independent judgment: The student will be able to autonomously understand, view, handle and modify a CAD model imported /exported in different formats.
Communication skills: The student will be able to discuss and present a 3D model using the appropriate terminology, both in oral and written form, through the preparation of reports relating to the exercises.
Ability to learn: The student will acquire an approach to the topics of the course that will allow him to promote the autonomous search for information through the existing technical and scientific literature.

Lectures and practical exercises

You will need to have a laptop in class. The teacher will provide support Powerpoints and the Rhinoceros license (CAD software used during the course)

Oral exam. The exercises carried out during the lessons will be commented on, which must be presented (on paper or by email) a few days before the exam, and some questions will be asked on the topics covered during the lessons
