The main content of this course is on how to apply the three-dimensional CAD software CATIA and CAE software ANSYS in engineering design and analysis. CAE software is based on CAD software. Thus, this course will start with the use of CATIA in model design first, and then with its powerful functions of surface and structure design. The coverage of ANSYS mainly contains the Workbench module and Fluent module. Static structural analysis, modal analysis, thermal analysis and hydrodynamic analysis will be introduced in this second part of the course.
