What is Simulation & CAE Software?

Simulation and computer-aided engineering (CAE) software allows engineers, analysts, and designers to perform finite element analysis (FEA), computational fluid dynamics (CFD), multibody dynamics (MDB), and optimization. Simulation software can also be referred to as CAE simulation software due to its association with CAE analysis and its application. Simulation software can create models based on mathematical data and place them in a predefined system. By analyzing these models, engineers study the relationship between model and system and the interactions that happen in a controlled environment. This helps predict performance, defects, and judge the potential product lifespan. CAE software reliability, vendor support, and critical design validation are the three factors buyers weight most heavily when simulation results feed directly into production decisions. Based on G2 reviews, engineering teams evaluate CAE simulation software by comparing solver accuracy against physical test data, the responsiveness of vendor support during setup and troubleshooting, and how early in the design cycle the platform lets them validate concepts before committing to prototypes. What Does Simulation & CAE Software Stand For? CAE stands for computer-aided engineering. The term computer-aided engineering is used as a technical term for simulation while the term simulation is what is often heard in the market when users refer to engineering simulation.

What are the Common Features of Simulation & CAE Software?

The following are some core features within simulation software: Computational fluid dynamics (CFD): One of the main forms of engineering analysis that CAE software performs is CFD. CFD is a way to model the behavior of both fluids and gases. This includes modeling the way they interact with one another as well as surfaces that they come in contact with. This feature can solve problems such as identifying incompressible and compressible fluids, laminar and turbulent flows, as well as multiphase flow problems. Finite element analysis (FEA): FEA is a numerical method used to solve engineering problems. This process is used to break down one large problem into a handful of smaller ones, called finite elements. Using this method, engineers can break down complex engineering problems into manageable pieces. One of the main ways engineers use FEA is to make model representations in which they can test how objects interact with one another, which provides an understanding of how an actual object would be affected by other physical forces. Examples are bridge modeling, car crash testing, and testing the structural integrity of any given object. Mechanical event simulation: Mechanical event simulation enables engineers to simulate how objects will react to certain events in real life. A good example of this is a simulation of how a mobile phone will interact with a cement floor in the event that it is accidentally dropped. Within the simulation, the software can indicate if the phone screen will crack or if any other permanent issues will be caused. The software can then suggest changes to be made to the phone to make it more durable and protected in the event of a dropped phone; when considering these changes, users can test the simulation until the product is adjusted to their liking. Electromagnetic simulation: Electromagnetic simulation allows users to simulate the electromagnetic properties of components or systems. This allows engineers in industries such as electronics and communications to determine how effective their component design is. Thermal simulation: Thermal simulation allows users to simulate how the physical properties of materials change with changes in temperature. Thermal simulation can be used to simulate areas such as electronics cooling, automotive thermal management, heat exchangers, pressure vessels, and other applications where users need to simulate the effect of thermal loads.

What are the Benefits of Simulation & CAE Software?

Speeds up design time: Simulation software speeds up the time it takes engineers to prototype and test how objects will perform in the real world. This allows product engineers to improve design performance well before a product is manufactured. A major example of this is how airplane engineers manufacture an airplane that can withhold the stress of landing on a runway. Within this process, there are so many variables to take into account, including the material, size, and speed of the airplane. Given the perspective of how many factors go into the safety and performance design of an airplane, one would think it would take countless days of manipulating the design to create a reliable product. However, CAE allows engineers to speed up this process by running simulations of plane landings and detailing exact ways in which the engineer can improve the design. Saves money: Simulation software is all virtual and done on the computer, hence the name “computer-aided engineering”. Since these simulations are all conducted virtually, it allows companies to save plenty of money by not having to manufacture countless designs before getting the final product correct. For example, car engineers can simulate how a car crash would occur before they even have to conduct the final experiment. This way, before car crash testing occurs, engineering teams already have a good sense of how the test will go. The result is having to spend less money on testing and trashing actual physical prototypes. Improves testing: When prototypes finally come down to physical testing, simulation software can help analyze what’s occurring during the test and identify any key faults that occurred. For example, if a car was tested for impact and the body of the car wasn’t strong enough to withstand a crash, simulation software can identify exactly what went wrong and suggest what needs to be changed.
