Electrification is everywhere! It brings energy efficiency into systems and also helps add new smart functionalities to products. The electric motor is a key element of such systems, converting electricity into mechanical power. It is multiphysics by nature. Electric machine engineers need to take into account various constraints from the early stage of the design, looking at electromechanical performance, as well as respecting thermal and NVH constraints. Simulations need to integrate these multiple physics and also coupling effects. Dedicated tools and streamlined multiphysics workflows are developed in order to reduce complexity and speed up the design.

The scalability performance of Altair Radioss software when running in parallel with up to 1152 cores, using mono and multi-domain techniques, was assessed for a large airplane-ditching model. Within the range of cores tested for the multi-domain (72 to 288 cores), the overall efficiency of the multi-domain simulations was significantly higher than the monodomain, taking almost a third of the time to complete the simulation when compared to the monodomain model for 72 cores. Both techniques have shown excellent scalability, with high scaling efficiency and with outstanding reliability of the results.

In order to ensure the safety of passengers and on-board personnel, finite element calculation is used at SNCF as part of the acquisition, renovation / modernization projects of trains as a decision aid and preparation for testing approval of trains. This is the main case of the mechanical strength of bolted and screwed assemblies, and more and more of the integration of composite materials into rolling stock structures in order to make them more capacious and less energy intensive. To do this, SNCF is developing methodologies to make the modeling of bolted assemblies and composite parts more reliable, as well as topology optimization. The tools of the HyperWorks suite, and in particular, the OptiStruct solver, allow SNCF to represent its types of materials, as well as these phenomena (bolted assemblies + topology optimization).

This presentation is by Program Manager Rob Jopson. It’s a given that the simulation models we build are intended to capture and predict physical behavior, the data used to create them is not always representative of the manufacturing process used to build the physical part. For layered composite parts in particular, this mismatch can cause significant overhead in managing the simulation data as the model is created and evolves. To solve this problem, Altair’s ply-based modeling methodology strives to maintain a 1:1 relationship between the simulation data and the manufacturing process, independent of solver. The latest developments of this methodology will be presented as a workflow in the new Composite Browser, available in HyperWorks. The recording is about 18 minutes long and was originally presented at the 2020 ATCx Composites.

This workshop on end-to-end workflow for modeling layered composites in HyperWorks was conducted by Program Manager André Möenicke. The recording is about an hour and 37 minutes long, and and was first presented at the 2020 ATCx Composites.

Variational asymptotic beam section (VABS) is a unique technology continuously funded by the US Army since 1988 and it has become a tool of choice in the helicopter and wind turbine industries for modeling composite rotor blades. With analysis of a finite element meshed cross section, VABS can compute the best set of beam properties for 1D beam analysis and also accurately recover 3D stress/strain distribution over the cross section. VABS has been integrated with HyperWorks and OptiStruct for Altair users to take advantage of this powerful technology for better design and analysis of composite beam-like structures.  The recording of the presentation by Dr. Wenbin Yu, CTO of AnalySwift, is almost 20 minutes long, and was originally presented at the 2020 ATCx Composites.

This presentation is by Markku Palanterä, Director Composites Business Development, Altair The composites design and simulation suite by Altair is actively developed with a holistic view to cover all stages of the process from material modeling all the way to the certification of composite structures. On the material modeling side, the focus is on continuous further development of Altair’s multiscale modeling technology for continuous fiber composites and injection molded plastics, but not forgetting further application areas, such as additive manufacturing. The ply-based composite modeling in Altair HyperWorks has recently undergone a major update to achieve an improved, more efficient modeling workflow. This together with planned further developments tie the modeling even better with the manufacturing to create realistic models of composite components as built. Altair’s solver technology for implicit and explicit analyses can utilize multiscale material models to accurately describe composite material nonlinear behavior up to failure. Altair’s unique composites optimization technology is being enhanced with the repeat laminate concept that provides added efficiency and user control over lay-up design. To further complement the idea of an integrated system with all the necessary composites capabilities, the Composite Stress Toolbox has been introduced in HyperWorks to support design and certification. The recording is about 22 minutes long and was originally presented at the 2020 ATCx Composites.

This presentation is by André Mönicke, Program Manager Classical composite analysis and certification methods continue to be used in a significant share of the composite design process. In particular, applying classical methods early in design, and integrating them with finite methods as soon as possible can allow faster decisions which will be rewarded when it comes time for certification. Altair’s latest developments to respond to those needs will be presented, covering the Integrated Composite Stress Toolbox and a Certification framework available in HyperWorks.

The recording is about 28 minutes long and was originally presented at the 2020 ATCx Composites.

This presentation is by Dr. Tomasz Garstka and Graham Barnes, LMAT Ltd. Manufacturing induced deformations and residual stresses are an unavoidable consequence of processing composites at elevated temperatures. A number of mechanisms have been identified causing residual stresses and distortions, including mismatch in the thermal expansion, cure shrinkage of the resin, consolidation and tool-part interaction. These mechanisms usually act collectively through the curing process and may lead to severe changes in the laminate characteristic. When cured and exposed to natural environment moisture swelling, as well as subsequent stress relaxation mechanisms lead to further geometrical changes. A novel cure simulation solver is demonstrated here with the application to typical aircraft components. The recording is about 10 minutes long and was originally presented at the 2020 ATCx Composites.

Dr. Royston Jones, Global CTO, Altair Consultancy, discusses how the global pandemic has been a catalyst for companies to harness the potential of simulation by reconfiguring their established design processes and traditional organizational structures. Technologies and methods that can deliver design feedback at the speed of development are already available; reducing expensive physical testing while injecting innovation into a company’s product. The rapid evolution towards a connected everything is having a huge effect on design. From autonomous and electric mobility to smart consumer products with new business models, development teams must now integrate simulations of controls systems into complex multi-physics models enriched by data captured by sensors in the field. Especially during concept development when rapid exploration of design ideas is essential, a full embrace of simulation will be essential to compete. The recording is about 19 minutes long, and was presented at the 2020 Global Altair Technology conference.

Dr Venkat Perumal, Senior Principle Engineer at Stryker Global Technology Center discusses the adoption of simulation in Medical Device industry and how it helps shorten the overall product development cycle time & cost.
