Our single resource offers clarity and insight into your advanced technology needs. ANSYS explicit dynamics tools are one part of our suite that delivers cutting-edge functionality — depth, breadth, a plethora of advanced capabilities and integrated multiphysics — providing confidence that your simulation results reflect real-world outcomes. The comprehensive range of solutions provides access to virtually any field of engineering simulation that a design process requires. Organizations around the world trust ANSYS to help them realize their product promises. Productive Environment The interface for our tools, ANSYS Workbench enables users to model all applications, from very simple to very complex. The platform can take weeks, sometimes months, out of a CAE process by eliminating manual file transfer, results translation and errors that often come from manual data entry. Workbench eliminates the labor required to produce updated simulation results brought about by design changes. It includes an extensive material library and automatic meshing, which further reduce problem setup effort and time. Advanced Study Modern CAD tools create geometries that are real- life accurate. Because most CAD geometry models are created for manufacturing purposes (but not for analysis), they often include overlapping surfaces, gaps and other dirty forms. ANSYS pre-processing tools clean, correct and reduce CAD complexity, making it possible to increase accuracy and speed. Explicit dynamics accuracy is, in part, a function of element size. Generally, the smaller the elements, the more accurate the results — but this requires longer compute times. ANSYS HPC techniques allow you to improve accuracy as well as to examine multiple designs in a given time. Reducing elapsed time for calculation leads to better, more optimized products. The end result is confidence that your product will thrive in the real world. Design Analysis and Optimization To understand a design's performance, you must identify the effect of all design parameters — which can easily lead to meeting product requirements. ANSYS DesignXplorer™ provides in-depth product understanding, illustrating the relationship between design variables and product performance — all before building a single prototype. Managing Simulation Data Simulation engineers — especially those performing explicit dynamics analyses — generate large volumes of data that need to be archived in a searchable format. ANSYS Engineering Knowledge Manager™ (EKM) enables capture and management of simulation data along with workflows and best practices. The tool can improve simulation efficiency and productivity. Eletronuclear S.A. used ANSYS explicit dynamics tools to simulate a hypo- thetical explosion near a nuclear power plant. The initial stage was simulated with the multi- material fluid (Euler) solver, as different types of materials can all be modeled in the same re- gion. The Euler FCT solver came into play after the explosion, as it simulates the response of ideal gases with second-order accuracy very quickly. 6 Courtesy ESSS and Eletronuclear S.A.
