Simcenter 3D
Structural Simulation

Simcenter™ 3D software for structural simulation offers a set of structural finite element (FE) solvers that form part of the Simcenter portfolio of simulation tools. They are used by engineers across all industries as part of their product development process to assess the structural performance of their systems.

Integrating the Simcenter Nastran solver , Simcenter 3D structural solutions offer scalable, open, and extensible capabilities for general and advanced analysts. They can be used on laptops, workstations and servers to tackle everything from small models to the largest high-end industrial models. Simcenter Nastran is available with enterprise licensing, which means it can be used independently of Simcenter pre/post solutions and can run on both Windows and Linux operating systems.

  • Increase confidence in final designs by virtually investigating your product's performance under all possible operating conditions

Simcenter 3D software addresses the engineering of complex products, offering significant improvements in simulation efficiency. With advanced capability 3D simulation technologies and powerful model preparation technology, Simcenter 3D offers new methods that increase realism and provide better insight.

Synchronous technology in Simcenter 3D helps reduce the time spent abstracting the model and editing geometry.

Meshes, loads, and boundary conditions are all associated with the basic design, so when your design topology changes, you can quickly update your simulation results. Solvers and analysis tools provide all the accuracy and speed you need for timely, simulation-driven insights.

Simcenter 3D includes solvers that let you dive deep into physics. Every application specialist will find cutting-edge technology that fits the problem – static or dynamic, linear or non-linear, composite or otherwise, including temperature-dependent materials and thermal loads acting on a structure.

In addition to structural solutions, Simcenter Nastran also allows the co-simulation of structural, thermal and flow physics. A dedicated multiphysics environment allows you to define the complete solution in a single model, making co-simulation easily accessible to a wide range of users.

The Simcenter 3D structural simulation solution is part of a larger multidisciplinary simulation environment and is integrated with Simcenter 3D Engineering Desktop at the core for centralized pre/post processing for all Simcenter 3D solutions. This integrated environment helps you achieve faster CAE processes and streamline multidisciplinary simulations that integrate structural simulation with other disciplines such as thermal simulation, fluid dynamics, multibody dynamics, or electromagnetic simulation.

Industry applications

Simcenter Nastran helps engineering manufacturers and vendors across many industries with their critical engineering computing needs so they can produce safe, reliable and optimized designs in ever-shorter design cycles.

Simcenter 3D Structures software is a unified, scalable, open, and extensible 3D computer-aided engineering (CAE) environment for simulation analysts. Simcenter 3D Structures is a package that combines Simcenter 3D Engineering Desktop, Simcenter Nastran environment and Simcenter Nastran Basic solver . Together, Simcenter 3D Structures provides best-in-class simulation modeling with the power to perform basic structural analysis with an industry-standard solver . The Simcenter 3D Engineering Desktop contained within Simcenter 3D Structures accelerates the simulation process, helping you efficiently build the simulation model you need from 3D geometry faster than traditional CAE preprocessors. THEThe Simcenter Nastran solver built into Simcenter 3D Structures allows you to seamlessly submit analysis models for static linear analysis, normal modes, buckling, and basic heat transfer. Simcenter 3D Structures also forms the foundation on which you can add additional solutions for dynamic structural, multi-step nonlinear, thermal, flow, acoustic, motion, optimization, and multiphysics analyses, all in a single environment.



Simcenter Nastran enables you to initiate digital simulation into your product development process, providing access to a large library of finite element types and material models, robustly handling load cases, and providing multiple sequences of efficient solutions for analysis. in models of unlimited size. You can also perform sensitivity studies based on these types of analysis.
