Our goal at Altair has always been to provide the best technology at the highest value to our customers, and the HyperWorks 2017 release is no exception. From model-based development to electromagnetics, from nonlinear analysis to structural optimization and exploration, the new release is filled with countless new and enhanced capabilities, making it the most comprehensive, open-architecture CAE simulation platform.
We’ll browse through some of the new products and enhancements highlights included in the release. If you like to dive deeper into some of the functionalities, a 30-minute long video overview can also be found here or by registering for one of the live or on-demand webinars at www.altairhyperworks.com/hw2017 .
Model-based Development Suite
solidThinking Compose™, Activate™ and Embed™ are three new products now part of the platform and therefore available under your HyperWorks license. They offer capabilities encompassing concept studies, control design, system performance optimization and controller implementation and testing.
According to Dr. Michael Hoffmann, Altair’s SVP for Math and Systems “Altair is focused on performance and functional requirements. Product development should start with simulation a lot earlier, before the first CAD feature is created. Use optimization and conceptual tools to first define the function and worry about the geometry later. In addition, Altair’s flexible licensing model allows users to easily move from concept-level through detailed designs, both at a system level and with deep physics exploration.”
solidThinking Compose offers a comprehensive math engine combined with a multi-language integrated development environment and 2D and 3D data visualization. Compose is fully integrated with HyperWorks and can directly Read/Write CAE data through the HyperWorks readers.
solidThinking Activate enables users to model and simulate multi-disciplinary systems and model-based design. Its intuitive block diagram environment allows users to model and simulate continuous and discrete dynamical systems, mix signal based and physical modeling and convert superblocks into C-blocks via automatic code generation. Activate integrates very well with the other HyperWorks products, for example enabling co-simulation of multi-body systems in combination with MotionSolve.
Last but not least, solidThinking Embed is the next generation of VISSIM Embedded, a graphical environment for model-based embedded development. The generated code is both highly-optimized and compact, which is essential for low-cost microprocessors and high-speed sampling rates.
The Highs and Lows of Electromagnetics
Flux™ for EM simulation of static and low frequency applications, and WinProp™ for propagation modeling and radio network planning are added as perfect complements to FEKO, focused on high frequency EM simulations related to antenna design, placement, RCS, electromagnetic compatibility (EMC), radiation hazard and bio electromagnetics.
Flux is particular well suited for electromagnetic simulation of static and low frequency applications related to electric machines, actuators and sensors, high power equipment and heat treatment. The latest release – in addition to being fully compatible with HyperWorks’ licensing – brings many new features that will accelerate the engineer’s creativity when designing electric equipment or electromechanical devices.
“With the HyperWorks 2017 release we followed our vision to continue focusing on simulation-driven innovation. We are now able to simulate more physics with improved HPC performance,” said Uwe Schramm, Chief Technical Officer, Solvers and Optimization at Altair. “In particular, with the addition of Flux for low-frequency EM simulation, we’re offering a complete multiphysics portfolio all linked through optimization.”
WinProp, on the other hand, with its advanced capabilities for wave propagation modelling and radio network planning is the perfect companion for FEKO. WinProp’s highly accurate and very fast empirical and deterministic propagation models are available for a wide range of scenarios: Rural, urban, indoor, tunnel, vehicular. It supports arbitrary transmitters including cellular and broadcasting sites, satellites, repeaters, and leaky feeder cables.
Material Modeling and Manufacturing
The introduction of advanced materials (e.g. carbon fiber-reinforced polymers or CFRP) and new manufacturing processes like additive manufacturing are changing the way companies make products. HyperWorks 2017 introduces some substantial innovation in order to assist our customers overcome these challenge.
Multiscale Designer is a tool for development and simulation of accurate models for heterogeneous material systems including laminated composites, honeycomb cores, reinforced concrete, soil, bones, and various others. Manufacturing offerings now include solidThinking “Click2” products for extrusion, casting and metal forming process simulation, respectively called solidThinking Click2Extrude, Click2Cast and Click2Form.
The latest addition to the family, Click2Form, is a sheet metal forming simulation software that enables users to optimize their products for manufacturing, with the consideration of early formability, material utilization and cost. In addition to providing the users with areas of possible failure due to tearing and thinning, Click2Form has comprehensive blank utilization capabilities that provides optimal blank shape including the best layout for blank nesting and the associated material cost.
Usability and Efficient Model Management
With products getting more complex and development time tighter, it’s paramount to cut through complexity and offer a fast and efficient user experience.
“HyperWorks 2017 adds key enhancements to the modeling and assembly capabilities of the software,” said James Dagg, Chief Technical Officer, User Experience at Altair. “Users can now communicate directly with their enterprise PLM system, storing libraries of parts and configurations of their models. Tasks like setting up a model with multiple configurations for different disciplines can now be done in minutes.”
In particular, HyperMesh® now offers a complete, robust solution for assembly and model variants management, expanding the part library and configuration management capabilities introduced in the previous release. Multi-pane views accommodate the newly added part set and configuration browsers: users can now assemble model configurations by simply dragging and dropping across different panes. The entirely new Part Library serves as a centralized library for parts currently being worked on, while offering various levels of version controls.
Important new features for crash and safety users have also been implemented. A brand new desktop tool called ConnectMe™ has been developed to efficiently manage, launch and update all the products within the HyperWorks suite.
Multiphysics Analysis and Performance
Major speed and scalability improvements have been implemented for all the Altair solvers. In particular, structural analysis capabilities for OptiStruct® have been further elevated to support the most complex nonlinear contact and material models.
Large displacement analysis is supported for all element types, and a new large sliding based contact formulation – continuous sliding – has also been implemented. For efficiency purposes, large displacement analysis can be defined to be subcase-dependent. Nonlinear transient analysis has been added and supports inertial effects, material nonlinearity, large displacements and contact.
On the optimization side, many new responses have been added, including seam and spot weld fatigue, solid element surface stress, Neuber correction for plasticity evaluation, and bore deformation constraints. A new Fail Safe Topology Optimization capability allows users to design fail safe concepts.
For fluid simulation (CFD), new turbulence and transition models have been implemented in AcuSolve to capture laminar to turbulent flow regime change. The latest release of the software contains an expanded suite of physics, enabling the simulation of transitional turbulent flows, immiscible multiphase flows, and advanced moving mesh capabilities. AcuSolve 2017 represents the first release of the solver targeted towards the simulation of multiphase flows.
In terms of computational performance, FEKO, OptiStruct, and RADIOSS leverage the most modern computer architectures and latest parallelization technology to generate solutions faster and make them more scalable on compute clusters.
