CAE DESIGN ANALYST PROGRAM

Updated: Oct 28, 2020

Special #LOCKDOWN Edition Learning Program for Mechanical Engineering Graduates

Introduction


Design and manufacturing is very vital to the progress of civilization. Before we dig deeper into CAE, let us first understand the basics of engineering design.

Engineering design of a product can be broken into four steps:


1. Problem definition – in the initial stages of product development, it is necessary to clearly define what the product is meant to achieve and / or do.

2. Creative process – once the objective of the product is identified, it is necessary to synthesize its form. This involves brainstorming sessions where designers and engineers meet and interact. Various forms are evaluated and selected into a set of few workable solutions.

3. Analytical process – Fitting the product into form is the next step. This requires strength and reliability analysis, cost determination, etc. This step is very important and iterative. Multiple solutions for the product may be evaluated till the optimal values are achieved. This is where CAE is blended with CAD. Using CAE software, trained engineers are able to evaluate various parameters of the desired object.

4. Prototype development & testing – this is where the theory is translated into practical. Prototypes are developed and tested, usually using 3D printers for rapid development.


Computer Aided Engineering


Computer Aided Engineering (CAE) is a fast emerging field that takes CAD to another level. While CAD is useful in creating 2D and 3D models of a product, CAE software allows a deeper engineering analysis of objects.


CAE thus finds applications in engineering fields like fluid dynamics, kinematics, stress analysis, finite element analysis, etc., typically where product development is concerned. CAE encompasses not only CAD, but also Computer Aided Manufacturing (CAM), Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD) and some other aspects of engineering. Simply put, you can create 2D and 3D objects using CAD, while you can analyze how that object will behave using CAE tools. The automated design tools provided by CAE have transformed engineering analysis from a ‘hands on’ experience to virtual simulation.
