Student's Perspective

  • Concepts of 2D and 3D drawing.
  • Enthusiastic for converting one’s imagination in real time 3D model.
  • Theoretical FEA and FEM knowledge will be added advantage.

Course Content

Introduction: The focus of this teaching package is on the practical aspects of linear dynamic analysis (with OptiStruct), i.e. what kind of solver settings are required to run dynamic analysis. The finite element program used is OptiStruct. The theory behind this method is deliberately kept very short.
