Engineering simulations enable testing and validation while products and systems are still in the design phase.
Engineering simulation uses advanced software to visualize, analyze, and predict the result of processes and the behavior of 3D product designs while those products and systems are still in development. The insights gained from engineering simulations help stakeholders make critical product design decisions in the digital phase, before moving to physical testing and prototyping—saving money, encouraging innovation, and accelerating time-to-market.

Many of the largest and most established industries in the world use simulation-based engineering to begin testing, validating, and predicting outcomes in the digital space well before entering the realm of physical testing and prototypes. These industries include automotive, aerospace, energy, electronics, construction, medical devices, chemicals and process manufacturing, civil and environmental engineering, and much more.
Engineering simulation can be used to analyze aerodynamics, vehicle handling, crash tests, and fuel efficiency in the automotive and aerospace industries; to test the structural stability of bridges, dams, and buildings before construction; to simulate chemical reactor and power plant heat transfer or analyze chemical reactions and electrical grid behavior; to simulate electromagnetic interference and semiconductor behavior in electronics; to simulate surgical procedures and medical device behavior; to simulate optimized waste treatment, material mixing, and construction processes; and so on.
Examples of simulation engineering are virtually limitless and apply to businesses of any size making products, structures, or systems based on 3D CAD models, not just to large industries and behemoth companies. Regardless of the product, engineering simulation software such as Autodesk CFD, Autodesk FusionMoldflow, FlexSim, and others can play an important role in several stages of production to simulate performance and behaviors, identify and fix problems, and accelerate time-to-market significantly.
In the early stages of product development, simulation lets engineers rapidly access dozens of different design choices for functionality, performance, and durability. Before physical prototyping, simulation can save time and resources by testing virtual prototypes under countless conditions. Simulating manufacturing processes before production can also assess production methods and processes instead of learning through trial and error on physical machines. Engineering simulation can create efficiencies in quality assurance and maintenance by predicting and preventing potential errors in the product and by simulating the wear and tear of extreme conditions, predicting maintenance needs before they arise.
Simulating product testing in the digital rather than the physical realm produces many tangible benefits, including:
With engineering simulation software, engineers can quickly analyze the performance of iterative design elements under various conditions to narrow down a short list of best options—all while in the digital space, significantly shortening time to market.
The ability to test and validate product performance as 3D CAD models in engineering simulation software can greatly reduce or even eliminate the need for physical prototypes. If physical prototypes are necessary, the process tends to be more efficient after going through rounds of simulation first.
By virtualizing simulation within software, engineers can test more features and variations faster and more often than they could using physical prototypes. That allows them to detect and fix problems earlier in the design cycle, which has a positive impact on quality and performance.
Maximizing the use of engineering simulation software reduces physical prototyping, shortens design cycles, detects engineering flaws earlier, and provides a central platform for collaboration—all of which heighten engineering’s efficiency and lower costs.
Because engineering simulation software can drastically reduce R&D costs and shorten design cycles, businesses can choose to pass some of those savings on to the cost of the product. Simulation software can also help find efficiencies in the materials used and the manufacturing process, leading to further product savings.

Simulation engineering refers to the development of buildings, infrastructure, products, and systems in which simulation software plays a role in visualizing, analyzing, and predicting the behavior of those things in real-world conditions.
The types of engineering simulation differ depending on their complexity.
Discrete event simulation (DES) models a sequence of events in a system to show how the system responds over time. It’s commonly used to analyze and improve production systems. Continuous simulation deals with a continuously progressing state of being, such as the load stress of a tank filling with water.
In process simulation, the simulated process, such as the manufacturing of a product, can identify potential problems or opportunities for efficiency. A Monte Carlo simulation looks at many random input variables to find the best output, such as matching a manufacturing process to the lowest cost for a level of demand.
A systems dynamics simulation is quite complex and takes in longer-term data flows rather than static inputs like discrete events. System dynamics simulations are useful for things like revenue projections and supply chain management.
Engineering simulation is important because it allows designers and engineers to begin testing and validating products, buildings, and systems early and often in the development process. This saves time and costs by reducing risks and optimizing designs within engineering simulation software, rather than with physical prototypes.
Engineering simulation software from Autodesk provides a centralized, cloud-connected environment for multidisciplinary collaboration and innovation, as well as informed group decision-making.
