Siemens has updated its Simcenter 3D, used by engineers and analysts to carry out multi-disciplinary analyses.
The tool is part of Siemens’s Simcenter portfolio of simulation and test solutions for predictive engineering analytics, used in industries like automotive, aerospace and industrial machinery. It works with data from any CAD source to offers generative design solutions for designers and advanced analysts.
Now, output from a topology optimization process can be used directly in the design process, without the need to recreate geometry, said Jan Leuridan, senior vice president for simulation and test solutions, Siemens PLM Software.
Also new with this release, hybrid modeling allows analysts to incorporate test-based data into their simulation models to achieve better accuracy within the simulation. Other enhancements include support for modeling sub-mechanisms within motion assemblies, faster computation time for analytical contact in motion models, and improved performance for interior and exterior acoustics simulation.
Also, engineers can now work directly with scanned data or an optimized shape to conduct more detailed simulations to ensure performance, he added.
Simcenter 3D also offers more accurate motion modeling, and more efficient acoustic and structural dynamics simulations than in past versions. It also provides expanded support for general-purpose nonlinear solutions, based on the NX Nastran multi-step nonlinear solver, Leuridan said.
Several of the enhancements target industry-specific workflows. Simulation engineers in automotive, aerospace, and heavy machinery companies benefit from the integration of universal connections support, which can help to efficiently build large system models with many connections and solve across several solvers, Leuridan said. Simcenter 3D also leverages the LMS Samcef solver for simulation of flexible pipes and hoses which are commonly used in a variety of industries.
By using Simcenter 3D along with HEEDS software for design exploration automation, engineers can explore the design space and generate innovative designs that meet more Sstringent design requirementsAlso, the tool allows fir efficient assembly of large motion models through management and re-use modular mechanisms, he added.
Other updated and new capabilities now included in Simcenter 3D are:
- FEM Adaptive Order, a finite element acoustics solver used to solve vibro-acoustic phenomena.
- Advanced analysis for composites as well as several updates that model connections in large assemblies as well as accurate simulation of flexible pipes and hoses.
- Hybrid modeling capabilities that allow analysts to incorporate test-based data into their simulation models to achieve better accuracy within the simulation.
- Support for modeling sub-mechanisms within motion assemblies
- Faster computation time for analytical contact in motion models
- Improved performance for interior and exterior acoustics simulation
“Siemens is executing on the Simcenter strategy it announced last year as evidenced by its ongoing investment in new simulation capabilities along with the accelerated integration of CAE technologies acquired over the past several years,” said Donald Tolle, practice director, simulation-driven systems development at CIMdata, a research firm in the product-lifecycle-management field.
