Built on the Siemens NX™ platform, it is also seamlessly integrated with NX CAD. With more enhancements than any previous version, Simcenter 3D, part of the Simcenter™ simulation and testing portfolio for predictive engineering analysis, aims to revolutionize how simulation engineers can reshape the design process in industries such as automotive, aerospace, and industrial machinery.
 
This latest version provides integrated topology optimization solutions with Convergent Modeling technologies to deliver comprehensive generative design workflows. These solutions enable more accurate dynamics modeling and more efficient acoustic and structural simulations. Simcenter 3D now offers enhanced support for general-purpose nonlinear solutions, based on the NX Nastran multi-step nonlinear solver, as well as advanced composite material analysis based on Samcef™. This latest version also offers new features to improve workflows across a wide range of industries, including modeling connections in large assemblies and accurately simulating flexible pipes and hoses.
 
“Siemens is delivering on the Simcenter strategy announced last year, as demonstrated by its continued investment in new simulation capabilities, along with the accelerated integration of CAE technologies acquired in recent years. The latest version of Simcenter 3D offers innovative topology optimization capabilities, applied within the context of generative design. Furthermore, it also brings together unique hybrid analysis technologies that extend the ability to model and simulate system dynamics for complex applications, such as high-frequency noise and vibration,” explains Donald Tolle, practice director, Simulation-Driven Systems Development at CIMdata. “These product enhancements ensure that Simcenter 3D remains a robust, scalable, and multidisciplinary CAE environment for simulation and analysis specialists.”.
 
Fully integrated with NX CAD and Convergent Modeling technology, Simcenter 3D now offers generative design solutions for advanced designers and analysts. For the first time, the results of topology optimization processes can be used directly in the design process, eliminating the need to recreate geometry. Furthermore, engineers can now work directly with scanned data or an optimized shape to perform more detailed simulations and ensure optimal performance. Simcenter 3D, together with HEEDS™ software, automates design exploration, allowing engineers to thoroughly explore a wider range of design possibilities and generate innovative designs that meet the most stringent design requirements.
 
With this new version, hybrid modeling allows analysts to incorporate data based on physical tests into their models for greater accuracy. Other improvements include support for sub-mechanisms within dynamic assemblies, faster calculation of analytical contacts in kinematic models, and improved performance for indoor and outdoor acoustic simulation.
 
Nonlinear simulation in Simcenter 3D has been greatly enhanced by leveraging improvements in NX Nastran and integrating the capabilities of the Samcef solver. In addition to its already robust capabilities for simulating nonlinear thermo-mechanical behavior in turbomachinery, Simcenter 3D offers greater support for general-purpose nonlinear solutions with more features, increased robustness, and multi-step nonlinear simulation algorithms, resulting in greater realism and faster solution times. Furthermore, residual stresses and springback effects can now be predicted when simulating the curing of composite materials.
 
Many of the enhancements are designed for industry-specific workflows. Simulation engineers in the automotive, aerospace, and heavy equipment industries will benefit from the integrated support for universal connections, which helps efficiently build large, system-based models with numerous connections using various solvers. Simcenter 3D also leverages the Samcef solver for simulating flexible pipes and hoses commonly used in a wide range of industries.
 
“Simcenter offers fundamental capabilities to help our customers innovate in their products,” says Jan Leuridan, Senior Vice President for Simulation and Test Solutions at Siemens PLM Software. “With our latest version of Simcenter 3D, we can integrate multiple distinct tool technologies under a single platform. Leveraging our extensive experience in geometry-based CAE, as well as our strengths in key disciplines such as structural dynamics, acoustics, mechatronics, and nonlinear analysis, we have enhanced Simcenter 3D to deliver more streamlined workflows and a broader suite of simulations to support performance-driven engineering.”.
