ANSYS explicit dynamics takes over when implicit isn't enough. For specialized applications, ANSYS offers the split-second insight you need along with ease of use and trusted results. If your product needs to survive impacts or short-duration high-pressure loadings, you can improve its design with ANSYS® explicit dynamics. Specialized problems require advanced analysis tools to accurately predict the effect of design considerations on product or process behavior. Gaining insight into such complex reality is especially important when it is too expensive — or impossible — to perform physical testing. The ANSYS explicit dynamics suite enables you to capture the physics of short-duration events for products that undergo highly nonlinear, transient dynamic forces. Our specialized, accurate and easy-to-use tools have been designed to maximize user productivity. With ANSYS, you can gain insight into how a structure responds when subjected to severe loadings. Algorithms based on first principles accurately predict complex responses, such as large material deformations and failure, interactions between bodies, and fluids with rapidly changing surfaces. An extension of our structural mechanics suite, explicit dynamics software shares the same graphical user interface (GUI), serving mechanical engineers who need to study highly complex problems — especially ones with high strain rates Sheffield Hallam University used our explicit solution to simulate ball-on-tennis- racket impacts. Their research centered on the coefficient of friction between strings and ball, and the position of the racket's balance point. The value of physical testing is limited in evaluating these potential improvements because of the high cost and time involved in building the huge number of new designs that need to be evaluated. "ANSYS explicit dynamics repeatedly enables us to solve complex explicit problems for our customers. We can get answers to them quickly due to the program's ease of use. The state- of-the-art solution methods and extensive material models produce accurate results, a necessity for creating follow-on business." Chris LeBoeuf Principal Engineer ABS Consulting and other complications that are difficult to solve with general-purpose implicit solution methods. A short learning curve is a hallmark of our products. The GUI speaks the language of the engineer or scientist. Consequently, the software's internal complexity is hidden from view, even as sophisticated, state-of-the-art mathematical algorithms resolve problems. Defaults are safe and reasonable values for most options, which means that you spend less time setting up and running problems and more time optimizing products for performance, durability and cost, as well as removing design flaws. In many cases, the accuracy of an explicit solution can be verified only via comparison with physical experiments. For some problems (such as explosions), it may be too expensive or impossible to perform tests. Yet ANSYS users around the world rely on the accuracy of explicit results: An extensive list of publications is testament to the correctness of our algorithms and models. 2
