Společnost Altair announces the release of its latest simulation solutions. Most functionality has now been added in connectivity simulation, building application (AEC) and electronic systems development (ESD) solutions. But let’s also look at the traditional simulation tools used in the automotive, aerospace, rail, and mechanical engineering industries. Here, too, there are a number of significant improvements.
Product development for a more connected future
One of the trends that Altair closely monitors and supports with its CAE tools is the area of connectivity. These include Internet of Things (IoT), vehicle-to-vehicle (V2V), vehicle-to-infrastructure communication (V2X), advanced driver-assistance systems (ADAS), 5G and soon 6G networks, and similarly. And the needs of these trends are reflected by the developers especially in the development of their tool for simulations of high-frequency EM fields Altair Feko. For example, you can now simulate larger or more complex antennas, perform faster and more accurate calculations, solve ADAS applications, and consider sensor types such as ultrasonic and infrared sensors.
Design of more sophisticated building structures
This latest version of simulation solutions contains a comprehensive solution for AEC (architecture, engineering, and construction) within the licensing system with Altair Units. You will use both specialized construction solutions Altair S-FRAME a S-CONCRETEnow with support for other standards, the benefits of fast simulations with Altair SimSolid, powerful networking with HyperWorks, and weather simulation solutions with Altair CFD.
Design of electronic systems
The development of so-called smart and connected devices and mechatronic systems around us is also accelerating the development of simulation tools for Electronic System Design (ESD). Printed circuit board (PCB) design solutions are expanding Altair PollExa free tool is now available PollEx for Altium. In the field of mechanical design of electronic devices, functions are expanding Altair SimLab for simulations of virtual drop tests and structural and thermal simulations. Solutions for power electronics also appear in the portfolio PSIM.
Solutions for every stage of product development
Now let’s look at the expansion and improvement of traditional “engineering-oriented” simulation tools, which we often encounter on the Czech and Slovak markets.
Up to 70% time savings can be achieved by the user of the new pre-processing solution (HyperMesh) thanks to the use of improved tools Model, Include, Subsystem and Solver browser. HyperMesh 2022 is a completely new entity “FE Geometry”, which allows the user to take advantage of working with topological entities, especially in cases where the original associated CAD model is not available for the finite-element model. Thanks to the new “Aggressive quality correction” function, BatchMesher networking technology provides a drastic reduction in the number of elements that do not meet the required quality criteria.
A novelty in post-processing (HyperView) is the previously introduced HWC recording function, which enables the capture and reproduction of the user’s workflow in the form of scripts. It is now compatible with other features, such as Hotspot Finder, Measure Curves, etc. Users who customize or extend standard HyperView features will appreciate the simplification of the scripting process provided by integrating parts of the MVP Toolbar into the HyperView core.
The Altair OptiStruct default solver has been extended with a range of tools and features in several areas. It is worth mentioning the introduction of strain-rate dependence or the possibility of inserting measured data into creep material. The method of entering heat transfer by free convection is significantly simplified, and Rayleigh damping at the material level can now be reported in the NVH area. In terms of fatigue, it is now possible to simulate the fatigue of soldered joints. Support for axially symmetric elements is introduced in the optimization area. The mentioned extensions are only a small fraction of all new updates by which the new version is extended.
One of the most fundamental benefits of the new version of this explicit solver is the improvement of many individual material models in combination with failure. There is also a whole new violation model and completely new material laws. A very interesting element of the equipment can be the ability to load the LS-Dyna code into Radioss. Currently, 160 keywords are supported. Radioss 2022 allows you to define a number of new parameters in commonly used functions, such as properties, contacts, loads, sensors, etc.
It is worth mentioning here the HyperLife Weld Certification module, which has been extended by the traditional approach assessment (SN) of welded and non-welded areas.
MotionSolve, MotionView, EDEM
Even with the MotionSolve solver, designed for multi-body dynamics (MBD) simulations, the user can look forward to significant time savings when loading and exporting larger reports. At the same time, the possibility of coupling with the EDEM bulk material simulation tool is improved, for example, saving intermediate results for restarting or modifying the simulation. Much progress has been made in driving dynamics simulations. A new empirical soft earth model for interaction with the tire is presented. This model can also be used in co-simulation with EDEM and PME FlexTire software. With the new tire inflation tool, it will be possible to simulate tire inflation or deformation while driving, and Applus + and XenomatiX tools can be used within APA. With Altair EDEM you can benefit from the speed of a multi-GPU solver for all particle shapes.
The biggest change is the support of the new type of optimization that customers have called for, and that is the possibility of parametric shape optimization. In addition, the user is provided with a related parametric approach to examining Design-of-Experiment (DOE) shape variants. Another fundamental and demanded change is the possibility of parameterizing the input values of active elements in the Motion module, depending on other state variables of the model, not only on time, as has been the case so far.
The new version builds on the previous gradual release of fatigue analysis to designers and brings the possibility of weld fatigue analysis using the Volvo method. In the area of frequency analysis, it facilitates post-processing by introducing frequency analysis with an envelope of multiple load cases and enabling the export of PUNCH result files.
Compared to the previous version, it allows not only the simulation of SLM metal printing, but now also the simulation of metal powder sintering (binder-sintering). At the same time, this time the results do not end with the prediction of production defects, but it allows to actively compensate the printed or sintered shape so that after deformation by the production process it corresponds as much as possible to the desired shape.
This tool is gradually becoming a full-fledged successor to Altair HyperForm. It is based on a clear user environment, which allows quick changes in pressing procedures and tool geometry. In addition to a number of minor improvements, it now has the opportunity to model pressed sheets in volume (using solid elements) and thus obtain greater accuracy of results.
HyperWorks CFD – AcuSolve, nanoFluidX, ultraFluidX
HyperWorks CFD has increased the speed and robustness of networking and geometry editing. Options have been added for model preparation, such as replacing an existing part with an external geometry file, easily deleting unnecessary calculations in the application, and more. The AcuSolve solver has been extended by the Euler-Euler multiphase model, which can include solid particles, including their temperatures. The new topological optimization tool has increased the speed and robustness of the calculation, as well as the support of porous zones. The nanoFluidX solver has been expanded with the possibility of exporting the heat transfer coefficient, and the ultraFluidX solver has been improved in the area of model preparation.
