Why Simulate?

The question “Why do we simulate?” isn’t a very straightforward or light-hearted one. If we change a few terminologies, the question can also be rephrased as:​

Why do we use computers and/or Computer Aided Engineering (CAE) software to solve engineering problems? ​
Why do we utilize numerical methods to solve mathematical models describing physical behaviours relevant to engineers scientists?

Before the detailed explanations are discussed on the abovementioned terminologies, the question can even be simplified to:​

“Why do we use tools (or technology) in general”?

This is a question most people with and without a technical background and mindset will be able to answer. Although there will be different opinions and priorities, the most prominent responses will be “to reduce efforts”, “to save time” and even “to increase consistency”. There will always be a strive to save time and money while maintaining quality in order to be competitive and relevant in any business environment. Not to mention product development and sustainability. Mankind will always make use of available knowledge and suitable tools to survive, and in certain circumstances, to thrive.

If this reason is brought back to our original question(s), the answer and motivations may seem obvious as most engineers are talented in finding ways to do more work with less efforts. However, certain tools in the engineering industry not only help to accurately speed up repetitive tasks and calculations, but also help us to gain insights into the science and engineering involved in product design and development. The time saved on complicated, elaborate analyses while ensuring certainty on product performance and quality, is the powerful gear-ratio that defines the requirement for engineering tools such as simulation technology. Increasing the business potential (i.e. product or solutions output) for a fixed amount of time is the definition of profit efficiency, the primary reason why successful businesses simulate during the design and development stages.

Elaborating on the primary drivers of time and money, we can add the secondary vital drivers that transforms an established business into a thriving, innovating enterprise, namely reduced time to market, reduced material usage, reduced scrap, increased consistency and quality, increased performance, increased innovation, research and development. Not to mention the process to capture knowledge and digitisation trends that Industry 4.0 provides.


A solution for a problem, or an outcome of an objective is measured on the final success as well as the performance thereof in terms of resources required. The solution or outcome, however, are very much dependent on the inputs and associated processes. The incentive for any successful engineer and business are to use the least amount of resources and time for the highest degree of outcomes. 

It is without a doubt that industry challenges or real world problems are often far removed from the examples in textbooks used to explain the theory. There are many ways to address the challenge, both adequately and accurately. But more often that not, a certain amount of uncertainty goes with the solution as the methods have certain assumptions associated with it. Non-conventional characteristics in the form of geometry, materials and load cases are a few contributors to the uncertainty. The uncertainties are accounted for by margins like extra material or conservative load cases, which in turn again influence the precious time-money ecosystem. A successful engineer, or rather business, always use the best available engineering knowledge and tools to honour engineering principals and commercial or economic integrity.

Computer Aided Engineering (CAE) software and simulation technology are one of the primary tools engineers and manufacturers use today to achieve the sustainable dynamic between business sense and engineering certainty. CAE software assist engineers and manufacturers to characterise designs, products and processes in order to eliminate uncertainties, potential flaws and, importantly, where the engineering time spent on effortful manual calculations exceeds the value of the result. Simulation technology expands the capability of engineering businesses to ensure competitive knowledge is developed sustainably.



It should be no secret for any lecturer, student or researcher, that science and technology has never developed independently from each other. Science and the understanding of the world around us has without a doubt help to development of technology. On the contrary, technology has open doors to scientific discoveries and gave insights into the world we live in.
The best example of the modern age is the influence and impact computers had on mathematics, physics and engineering. Matrix algebra, solving equations simultaneously and the Finite Element Method (FEM), to name a new, is not a 20th century invention. These ideas and techniques originated well before then but has only reached its full potential with the dawn of the computer. MSC Software was one of the very first pioneers to use digital technology to solve complex, extensive mathematical problems and equations for NASA during the early stages of the space race. This new bridge between science and technology found its way into structural analyses and other forms of engineering applications. The advances, has without a doubt changed the way we see the world, what we learn from it and how we solve problems. This has created a completely new platform to develop and understand science. Thus, if our objective is to be the next generation engineers and scientists, we can’t separate science and technology from each other.
Understanding the fundamentals and technical aspects behind every physical and engineering science is vital. Failing to do so, ultimately result in the decay of knowledge, loss of profit and even life. How we apply those fundamentals and understanding and how we go about to solve it for our design and problem purposes, is a completely different matter. There are several different and techniques ways to address this challenge in many forms and shapes. Computer Aided Engineering (CAE) is a key term closely associated with the activity of using digital technology to solve engineering sciences and challenges.

Hexagon | MSC Software is a world-leading CAE simulation technology provider and provides powerful software tools not only to design and develop products, but also to learn, apply and visualize engineering principals. The technology allows the lecturer, student and researcher to understand basic principals and to move from conventional design principals (based on the non-computational methods that support it) to more advanced, sustainable solutions. The software gives insights to the behaviour and performance of ideas and concepts without any experimental setups or part manufacturing. The CAE technologies covers almost all the engineering disciplines, fields and specialisations.
