The 3DX Simulation Experience: Combining the Best of Both Worlds

The 3DEXPERIENCE platform integrates the strengths of CATIA's advanced CAD capabilities with SIMULIA's powerful simulation tools, creating a unified environment for both. This ensures continuity and reduces errors during data transfer. It supports collaborative workflows so that design and development teams can work together efficiently.

SIMULIA offers a comprehensive range of simulation software for various disciplines, including structural simulation, computational fluid dynamics, electromagnetic simulation, multi-body dynamics, vibro-acoustic simulation, Finite Element Analysis and stress analysis of composite materials. This range enables companies to model, analyze and optimize their products, processes and workflows.

SIMULIA's software portfolio is available as a stand-alone suite of tools for simulation and analysis or encapsulated in the 3DEXPERIENCE platform. CATIA, part of this platform, combines 3D CAD with advanced modeling and simulation techniques. It enables the modeling of cyber-physical systems and allows the simulation of products, processes and systems in a virtual environment.

By integrating SIMULIA and CATIA, 3DX breaks down cumbersome silos and ensures digital continuity. It enables a seamless transition from advanced design to detailed simulation, allowing mechanical designers to perform complex simulations such as finite element analysis (FEA) and composite design without having to switch software. By eliminating the need to import and export data between different tools, this integration reduces manual tasks and errors. It enables in-depth analysis during the design phase, resulting in accelerated development and improved efficiency.

With CATIA's robust 3D design and modeling tools and SIMULIA's comprehensive simulation capabilities, you get the best of both worlds for advanced design and detailed analysis, leading to more accurate results and optimized product development.

Future Changes: What’s Currently Stimulating Simulation?

Simulation has evolved from being a purely physical prototype-based process to a highly advanced digital approach. Early computer simulations required extensive manual inputs and specialized expertise. However, advancements in computing power have made simulations more accurate and user-friendly. Today, automation is becoming a significant trend in simulation software. This trend is driven by advancements in user interfaces, scripting capabilities, and AI-driven tools, which streamline workflows and enhance productivity.

Automation enables simulation software to automatically set up simulations, suggest optimal parameters, and even propose design changes based on simulation outcomes. This reduces time-consuming tasks like manual data input, error correction, and repetitive configurations, allowing engineers to focus on analysis and decision-making. Automation can also facilitate easier interpretation of results and improve communication between teams by providing clearer visualizations and insights. User interfaces are more intuitive, guiding users through the simulation setup and suggesting solutions to potential problems. This automation streamlines workflows and reduces the need for specialized expertise. Generative design and automated modeling are also contributing to a new age of simulation, where engineers can quickly explore countless design options and identify the best solutions.
