Support for convergent modeling technology and topology optimization solutions

Siemens PLM Software announced the release of the latest version of its flagship multi-computer-aided engineering (CAE) program, Simcenter 3D.

Simcenter 3D is a standalone, advanced CAE application for professionals that can work with data from any CAD source. Built on Siemens' NX platform, it integrates seamlessly with NX CAD.

Simcenter 3D is part of the Siemens Simcenter portfolio, a simulation and test solution for predictive engineering analytics. With newly enhanced capabilities, simulation engineers are expected to accelerate innovation in design methods across various industries, such as automotive, aerospace, and industrial machinery.

Simcenter 3D supports Convergent Modeling technology and seamlessly functioning topology optimization solutions. This enables a comprehensive Generative Design workflow. These solutions allow for more accurate motion modeling and efficient acoustic and structural dynamics simulation.

In addition, Simcenter 3D has been able to extend its support for general-purpose nonlinear solutions based on the NX Nastran multi-stage nonlinear solver and advanced complex factor analysis based on the LMS Samtech Samcef software. With various enhanced features, workflows in various industrial fields can be improved, such as large-scale assembly modeling connectivity and precise flexible pipe and hose simulation.

Donald Tolle, Head of Simulation-based System Development at CIMdata, stated, "Siemens is rapidly integrating the CAE technologies it has acquired over the past few years. At the same time, we are actively executing the Simcenter strategy announced last year, including making continuous investments in new simulation capabilities. The latest version of Simcenter 3D offers innovative features for topology optimization applied to generative design. Furthermore, we have applied Siemens' proprietary hybrid test and analysis technologies to enhance system dynamics modeling and simulation capabilities for addressing issues such as high-frequency noise and vibration in complex applications. Through these enhancements, Simcenter 3D will continue to provide a powerful, scalable, and diverse CAE environment for simulation and analysis professionals."

Through hybrid modeling, a new feature of the product, analysts can integrate test-based data into simulation models to further enhance simulation accuracy. Other enhancements include support for modeling sub-mechanisms within motion assemblies, reduced computation time for analysis points in motion models, and improved internal and external acoustic simulation capabilities.

Simcenter 3D has significantly enhanced its nonlinear simulation capabilities by integrating the features of NX Nastran and the LMS Samcef solver. Simcenter 3D not only features powerful capabilities for simulating the nonlinear thermodynamic motion of turbomachinery, but also expands support for general-purpose nonlinear simulation, enabling multi-stage nonlinear simulations for more elements and algorithms. This has resulted in richer realism and reduced solution times. Additionally, it supports the simulation of curing complex elements, allowing for the prediction of residual pressure and springback effects.

In addition, capabilities to improve industry-specific workflows have been enhanced. Simulation engineers at automotive, aerospace, and heavy equipment companies can now efficiently build large system models using numerous connections through integrated universal connectivity support, and solve problems by utilizing various solvers. Simcenter 3D also leverages the LMS Samcef solver for the simulation of flexible pipes and hoses commonly used in various industries.
