Computer-Aided Engineering - Fundamentals

The purpose of using CAE or Computer Aided Engineering is to implement computer software to improve product designs. Computer Aided Engineering also aims to resolve engineering problems in different industries. CAE includes designing, validating, and optimizing products, manufacturing processes, and tools. 


The CAE process typically comprises the engineering process's preprocessing, ongoing, and post-processing phases. The engineers design the product in the preprocessing phase—a mathematical formulation process in the next phase of the CAE procedure. The last phase is the post-processing phase, in which the engineering results are reviewed before implementation.   


What are the applications of CAE or Computer-Aided Engineering? 


CAE, or Computer-Aided Engineering, is based on various engineering disciplines. These are as follows: 


  • Thermal and fluid analysis (computational fluid dynamics or CFD is applied in the process)
  • Finite Element Analysis or FEA for Stress and dynamics analysis ( to carry out components and assemblies)
  • Mechanisms' kinematics and dynamic analysis 
  • 1D CAE or mechatronic system simulation (multi-domain mechatronics system design)
  • Mechanical event simulation (MES)
  • Application of FEA for Acoustics analysis/boundary element method (BEM)
  • Analysis of Control systems 
  • Product or process optimization 
  • Manufacturing process, including casting, modeling, and die press forming, initiating 


Advantages of the CAE (Computer-Aided Engineering)


The advantages of CAE or Computer Aided Engineering include the following: 


  • The CAE performance can be quickly asses for manufacturing designs.
  • You can get insight into the overall system performance, design development process, and design changes.
  • The CAE data and its management is integrated, allowing you to check the designing process on a broader scale. 
  • CAE helps your organization manage risk and get an overview of the implications of the design performance. 
  • When properly implemented, the CAE is the most integrated engineering plan for addressing engineering issues. In the manufacturing process, it enables quick resolution of any engineering issue. The proper implementation of CAE promotes cost-effective product manufacturing.
  • CAE reduces design and drawing errors. It offers a robust design plan in the manufacturing process. 
  • The CAE is beneficial in promoting the manufacturing process. You can also use CAE to improve the existing designs.   


What is the CAE Process?


The CAE process includes the following procedures: 


  • In the first stage of the CAE process, CAD software is used to design the product, system, or object. However, the parameters of the product, system, or thing are assessed by engineers. The parameters of concern in the CAE process include geometry, properties, and the entity's limitations. 
  • In the next stage, engineers evaluate the FEA, NVH (vibration, noise, and harshness), and CFD to get an overview of the CAE process. 
  • In the last stage of the CAE process, the parameters of the object or system are considered by the engineering team to ensure optimal results in the manufacturing process. A similar approach is made several times to achieve the desired results.  


CAE tools 


CAE tools are growing popular for offering easy computational input. These software tools can cover a wide range of designing. The standard CAE tools are as follows:


  • CATIA
  • HyperMesh Software


Conclusion


Computer-Aided Engineering (CAE) is a powerful tool for engineers to analyze and optimize designs, reducing development time and costs while improving product performance. By leveraging computer simulations and models, CAE helps engineers identify potential design flaws and make informed decisions before physical prototypes are created. As technology advances, CAE will continue to play an increasingly important role in the engineering design process.
