Addressing Design Development Challenges Through Simulation Driven Platform
Automotive suppliers are facing many challenges in having in-house simulation capabilities compared to that of OEM’s. One of the ways to overcome these challenges is to invest in simulation technologies that require an affordable initial investment, the ownership cost of which is low, the codes are reliable & proven, and the suite of tools provide suppliers access to a broad range of solvers (a true multi-physics environment) helping them pick and choose the solvers as per their simulation requirements. In the early stage of in-house simulation implementation at Endurance Technologies, HyperWorks was being adopted primarily for pre and post processing due to its extraordinary FE modeling solutions. With constant support, Altair team has helped Endurance in exploring and implementing various HyperWorks solvers at Endurance Technologies.

Integrated Systems Simulation from Requirements
Ed Wettlaufer, Technical Manager Mechatronics Group, Altair [on behalf of NAVAIR]


Government solicitations for proposals, or RFPs, for aircraft and airborne systems require preliminary designs with enough fidelity to accurately predict performance, in order to prove the design's ability to meet the Governments performance requirements. Modern high-performance computing provides the leverage to execute previously expensive analyses in areas such as computational fluid dynamics. The results of these high order analyses can be used to populate parameters in 1D systems models which can be easily coupled to medium order models from other disciplines. These capabilities allow the design engineer to rapidly iterate to levels of model maturity and accuracy not achievable years ago, resulting in high levels of confidence in the designs performance predictions in unprecedented time.

Moving forward, Altair engineers will employ Multiphysics and co-simulation to execute the Engineering and Manufacturing Development phase (EMD) for one subsystem of the preliminary design developed in the afore mentioned pre-acquisition phase.

A Multifunctional Aerospace Smart Skin Emerges from Computational Models and Physical Experiments
The capability to assess the current or future state of the health of an aircraft to improve safety, availability, and reliability while reducing maintenance costs has been a continuous goal for decades. Many companies, government agencies, and academic institutions have become interested in Integrated Vehicle Health Management (IVHM) and a growing effort of research into “smart” vehicle sensing systems has emerged. Methods to detect damage to aircraft materials and structures have historically relied on visual inspection during pre-flight or post-flight operations by flight and ground crews. More quantitative non-destructive investigations with various instruments and sensors have traditionally been performed when the aircraft is out of operational service during major scheduled maintenance. Through the use of reliable sensors coupled with data monitoring, data mining, and data analysis techniques, the health state of a vehicle can be detected in-situ.

Real-Time Foundation Monitoring for Omnifor
In the western part of the Netherlands, the soil has insufficient bearing capacity to allow for the construction of buildings and houses. To overcome this issue, buildings in this area have been built on timber pile foundations. These foundations have to be fully submerged in water to avoid pile deterioration from rotting and fungi. Property owners wanted a way to monitor the structural condition of their timber pile foundations. Omnifor teamed up with Altair SmartWorks and created a platform for structural health monitoring to track any signs of deterioration or shifting of the foundation. Data is collected at a specific rate to track the evolution of the deterioration along with an estimate of how long the property owner has until repairs are necessary.

Concept Design for Plastic Parts - Better and Earlier Decisions with CAE Driven Design
Traditionally, products are created with a draft, which is then specified by taking into account external factors. The next step is to validate, test them as prototypes and adapt the design. If simulation is used as a virtual test, this cycle can be accelerated.

The foundation for a successful design is set in the concept phase.

This raises the question of how simulation can be used as a motor for creative solutions and how it can be used as a groundbreaking basis for decision-making in the early phase of product development.

With the simulation-driven design approach, you can achieve early design maturity, efficient material utilization and shorter development times in the development of complex plastic components. Using the example of a front-end module, Code Product Solutions and Altair will demonstrate efficient product development in the recording "Concept Design for Plastic Parts".

Explicit Dynamic Simulation of Tool Drop on the Outer Wing of the Swift020 Unmanned Aerial System using Radioss®
The successful launch of a new platform UAS is a comprehensive design engineering and manufacturing endeavor. The full lifecycle must consider maintenance and replacement components. As these requirements often require the use of tools (i.e. screw drivers, wrenches, pliers), the concern became apparent that as the flight surfaces are minimum gage, heavy tools dropped on the structure could cause irreparable damage. The objective of this project was to determine the specification for maximum maintenance tool weight such that, if dropped from a nominal height of 0.762 meters, would not cause permanent damage to any part of the Swift020 UAS. The Altair solution included a Radioss Explicit Dynamic Impact Simulation.

Quadcopters: From System Modeling to Real-Time Simulator
Presenter: John Straetmans, Computer Engineering Student, University of Michigan

This project attempts to build an accurate real-time (RT) drone simulator through the full integration of a 1D functional model of a drone created in Altair Activate®, along with its corresponding geometry, into Unreal Engine via the Functional Mock-up Interface (FMI) standard. Then, VR, peripheral controllers, and other functionalities were added to the representation. This task was accomplished by modifying the Altair RT Vehicle Package, making it able to handle not just vehicles, but any system model located in an FMU for co-simulation, in this case a quadcopter model. Once the FMU containing the Altair Activate® drone model was successfully loaded into Unreal Engine, the tools provided by the application allow additional features to be added, such as VR support. By implementing an FMU, together with its geometry, into Unreal Engine, we can visually analyze the dynamics of the system to further verify the drone model and its performance. In the future, this integration process should be facilitated to automatically load any FMU following just a few steps.

Solving Challenges in Electric Motor Design
Presenter: Berker Bilgin, Assistant Professor of Engineering (ECE) at McMaster University and co-founder of Enedym Inc.


Electric motors in general, are made of certain parts, such as the stator, rotor, coils and magnets, and mechanical parts. These parts might look simple and bulky from the outside, however, the highly interrelated relationship between the geometry of these parts, characteristics of materials, and the way the current is controlled, defines the cost, size, efficiency, performance, and lifetime of the motor. In electric motor design, multidisciplinary aspects are highly interrelated. The effect of various parameters on the electromagnetic, thermal, and structural performance should be investigated together to come up with an optimized design. This is possible by developing the platforms where the multidisciplinary aspects are modeled in a software environment, as we are doing with Altair software.

Fatigue Life from Sine-on-Random Excitation

ADAS Simulation Under Severe Vibrations
Automotive radars are becoming standard equipment on vehicles. Their purpose is to adjust the distance between vehicles and/or alert the driver when dangerous situations arise. Several antenna architectures are used to cover the different safety functions in complex bumper/car chassis environment where the side
effects become more and more significant on the radar performances. Hence, automotive radar integration process becomes a very important
topic. Weak radar integration will generate gain loss, high side lobes levels and angular errors. Those degradations will impact the radar range,
the main radar axis (BSE) and the radar detection quality (resolution, ambiguity, discrimination).
