Computer-Aided Engineering

Computer-aided engineering (CAE) is the use of computer software to simulate performance in order to improve product designs or assist in the resolution of engineering problems for a wide range of industries. This includes simulation, validation and optimization of products, processes, and manufacturing tools. CAE software allows a deeper engineering analysis of objects. It’s applications in engineering fields like fluid dynamics, kinematics, stress analysis, finite element analysis.CAE has transformed engineering analysis from a ‘hands-on’ experience to virtual simulation.

The future of CAE in the product development process

Modern products are more complex. They include smart systems, which lead to an increased need for multi-physics analysis including controls, and contain new lightweight materials, to which engineers are often less familiar. CAE software companies and manufacturers are constantly looking for tools and process improvements to change this situation. On the software side, they are constantly looking to develop more powerful solvers, better use computer resources and include engineering knowledge in pre- and post-processing. On the process side, they try to achieve a better alignment between 3D CAE, 1D System Simulation and physical testing. This should increase modelling realism and calculation speed. On top of that, they try to better integrate CAE in the overall product lifecycle management. In this way, they can connect product design with product use, which is an absolute must for smart products. Such an enhanced engineering process is also referred to as predictive engineering analytics.

Advantages of CAE:

  • Since simulating reality is less time consuming, CAE processes save on time and money.
  • CAE reduces the errors in the design and drawing process.
  • The impacts of changing parameters on a system can be studied with more accuracy.
  • Robustness and performance of components and assemblies can be analyzed.
  • CAE allows for easy visualization and improves designs.
  • CAE aids ease of manufacturing.


The ANSYS Workbench environment is an intuitive up-front finite element analysis tool that is used in conjunction with CAD systems and/or Design Modeler. ANSYS is a general purpose software, used to simulate interactions of all disciplines of physics, structural, vibration, fluid dynamics, heat transfer and electromagnetic for engineers.

So ANSYS, which enables to simulate tests or working conditions, enables to test in the virtual environment before manufacturing prototypes of products. Furthermore, determining and improving weak points, computing life and foreseeing probable problems are possible by 3D simulations in virtual environment.
