Altair’s products for multi-body system simulation (MBS) – MotionView, MotionSolve, and Inspire Motion – form a key component of multi-disciplinary system simulations. In this presentation, we will look back on several achievements this year, in the form of customer successes as well as recent enhancements to these products which significantly extend the depth and breadth of capabilities. Some of these application examples also involve connections from MBS to other Altair technology or to 3rd-party technology such as to Altair OptiStruct (for flexible bodies and light-weighting) and Altair Activate (for hydraulics) and EDEM (for discrete element modeling of bulk materials).

This presentation shows a modeling process to quantify the position/speed sensor (e.g, encoder) effects on an e-motor, and corresponding control system for a concept traction motor similar to the Nissan Leaf. The integrated solution of the e-drive is carried in Altair Activate as a system builder, using other Altair solutions e-motor solutions in FluxMotor and Flux to generate data for the e-motor itself, as well as the optimal current values for the Field-Oriented Contoller. The inverter is driven with efficient space vector pulse width modulation. The integrated solution also supports different levels of modeling fidelity for the system components, for example for the e-motor where either direct co-simulation with Flux for detailed finite element analysis or a reduced order model (ROM) using look-up tables. In this way, sensor design parameters can be evaluated within an accurate system of the e-drive to improve performance and efficiency.

As more products enter the market that simulate real world experiences, consumers' expectations are rapidly increasing. To meet these rising expectations the hardware and controls required are becoming more complex while maintaining time to market and cost. To achieve this, efficiencies are required in the control’s development and hardware tools chains. Wahoo Fitness and Altair collaborated to create the new Wahoo KICKR Bike utilizing a Model-Based Design approach to controls development combined with a simulation driven design process to meet the high expectations of the bike trainer community.

Achieving the targeted brand image in a short development cycle time with minimal or zero prototypes is a major challenge faced by EV companies. To overcome this challenge, Altair, HBK and Romax have jointly developed a simulation driven process coupled with capabilities to virtually experience the noise and vibration characteristics, giving engineers a way to obtain real time performance feedbacks as the vehicle is being developed. This joint presentation on the proposed NVH development process covers a wide range of topics, including benchmarking, target setting, full vehicle and motor gearbox simulation loadcases, troubleshooting, optimization and stochastic analysis, and playback of simulation results for subjective evaluations, with a number of new technologies representing the global best practice in sound and vibration design and development. Join us to explore ways to control the sound and vibration characteristics of the vehicle, achieve the right sound, and avoid common NVH pitfalls, while accelerating time to market utilizing and experiencing virtual NVH prototypes.

The 4th industrial revolution or the digital enterprise will re-build the business models in various industries through connectivity. The drivers for 5G NR in industrial IoT (IIoT) networks are (i) increased productivity, (ii) digital transformation through wireless technology and (iii) the use of private networks. The industrial IoT (IIoT) network will be scalable in connectivity, and number of devices and will be designed to deliver optimal performance for all industrial applications using key LTE and 5G NR features like URLLC, mMTC, 5G positioning, time sensitive communications (TSC) and to a lesser degree eMBB. This presentation begins with an overview, use cases and requirements for IIoT. The presentation discusses the foundation for URLLC in NR which was laid out in 3GPP Rel 15, mainly in support of IIoT, and URLLC enhancements in Rel-16, NR Positioning (Rel-16), TSC (Rel-16) and a version of NR known as NR-Light which is planned to be introduced in Rel 17. NR-Light aims to address use cases that cannot be met by NR eMBB, URLLC or mMTC. The system performance for an indoor ray traced factory using key 5G NR features like URLCC and TSC is presented.

David Yáñez presents at the UK ATC 2019. Vortex Bladeless is a Spanish start-up that is developing a new wind energy technology. Its key characteristic is the minimization of mechanical elements that can be worn by friction. In the first stage, its application area seems to be distributed energy. For its development, CFD tools are being of vital importance. Both the fluid-structure interaction and the behavior of the magnetic fields in the alternator are being studied mainly with this type of tool. The results obtained are being contrasted with experimental results obtained both in wind tunnel and in real application environments.

A general vision of the technology, the strategies used for the integration of the different physical phenomena involved and the path traveled for its development will be exposed.

Presentation by Vincent Ardon, EMC Engineer at ALSTON Tarbes.

Due to the environment, more and more compact with signaling systems functioning from a few dozen of Hz to GHz close to train motors or traction cases, the prediction of magnetic field emitted by motor cables could help train designers early in the process and avoid EMC problems encountered at the end on the first train tests.

Magnetic field measurements are performed close to motor cables on a test bench with SiC power module generating high dV/dt (up to 11 kV/µs) and a 3-ph motor whose high frequency equivalent circuit (10 k-100 MHz) was established thanks to differential and common mode impedance measurements with Mirafzal method.

Several configurations are tested and modeled in Altair Feko: motor cables length (30 and 45 m), power module source signal (mono-pulse or PWM), and metallic environment (copper and iron plate above cables). Finally, results of comparisons between measurement and Feko simulations on the frequency range 1 k-10 MHz are presented.

Presentation by Nicolas Fagnoni, Cavendish Laboratory, University of Cambridge.

The University of Cambridge and the Cavendish Laboratory are closely involved in the design and development of two new radio-telescopes: the ‘Square Kilometre Array’ (SKA) and the ‘Hydrogen Epoch of Reionization Array’ (HERA). Using different approaches, these two radio-interferometers in particular are going to study the formation of the first structures of the early universe, by measuring the evolution of the distribution of the neutral hydrogen present in the intergalactic medium. Thus, it will be possible to probe a period between 115 million and 1.3 billion years after the Big Bang for HERA, and even up to 2.1 billion years for the SKA.

In this presentation, Fagnoni gives a brief overview of these two radio-telescopes, and explain how we used electromagnetic simulations to design these antennas before building the prototypes for validation.

Presentation by Gilles Vogt, Inteliance Technologies.

When adding a radome to any network antenna, the transparency of the radome is a major concern, especially when the networks is tightly designed. A very large radome (6m long) has been modeled in Altair Feko (full wave MLFMM) in the GHz band to quantify the attenuation due to the radome, but also its impact on signal phase. The model includes an equivalent sandwich material obtained from an optimization based on a 2D infinite plane model using Green’s functions.

Presentation by Dr. Ahmadreza Jafari, Radio Reception and Antenna Expert, & Phillippe Boutier, Référent RadioFréquence at Renault.

In this presentation, different examples of Renault RF simulations regarding antenna applications such as keyless entry and ignition, AM/FM/DAB radio, radar and V2X are explored. Simulations for keyless entry and ignition are performed using Altair Feko at 125 kHz and 433 MHz. The aim is to define antenna placements to achieve the required hand-free detection zone and remote-control range. Concerning AM/FM/DAB radio, rear-screen and foil antenna radiation patterns are simulated to optimize fine tuning validations. For the radar antenna, impact of the environment around the antenna is explored by simulation.

This presentation also deals with a simple and complete simulation approach for V2X, in which WinProp propagation scenarios are combined with various antenna solutions.
