Simulation V Atoms
Dr. Nuno Lourenco, Senior Manager Body Engineering at Jaguar Land Rover presents at the 2019 UK Altair Technology Conference. The increasing complexity of mechanical systems across multiple industries poses challenges to simulation activities, where solvers, pre- and post- processors often fail to capture all control variables and noise factors affecting a system and can lead ultimately to a gradual loss of credibility to simulation tools and engineers. A hypothesis is presented that the answer is to tackle that system complexity through simplicity, in an approach that is more akin to software development rather than traditional mechanical
system design.

Taking on the Shell XPRIZE with Help from a Digital Twin

A New & Revolutionary Way to Collect Energy from Wind
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.

Development of the Next Generation Civil Tiltrotor
Leonardo’s Product Roadmap and the Associated Design Challenges. The Multi-Disciplinary Requirements of Tiltrotor & Other Lightweighting Studies.



This is a keynote presentation from the UK Altair Technology Conference 2019 by David Matthew, Lead Engineer at Leonardo. David joined Westland Helicopters as an undergraduate trainee in 1990, studying Mechanical Engineering at Imperial College and joining the Stress Office following graduation. Since then, David has worked within the airframe structure system group on a range of military and civil helicopter projects including the AW101 and AW189 helicopters, becoming a lead specialist in fatigue and damage tolerance, structural analysis, testing, and qualification. On the AW189 project, he led the analysis and qualification activities from preliminary design through to certification.



For the last year, David has been the Structures Lead Engineer for the Next Generation Civil Tilt Rotor project. This is a collaborative research project, which is part of the European Union Clean Sky 2 programme. This project is to develop technologies to support a large tiltrotor aircraft and to demonstrate these on a test demonstrator aircraft.

Vehicle NVH Design & Development Using NVH Director
Malcolm Hardy, Principal Engineer Vehicle NVH at Jaguar Land Rover presents at the UK Altair Technology Conference 2019. With an increasing number of vehicle programmes, propulsion variants and body styles on a range of different vehicle architectures, it is increasingly challenging to ensure that control models are consistent to allow comparable CAE assessment.



This is essential to allow key engineering decisions to be made and becomes even more critical as Jaguar Land Rover develop Full Vehicle NVH Simulator models to enable subjective assessments and sign-off before a physical prototype is built. This leads to a requirement for a consistent and robust process, independent of the user, for assembling models and applying load cases across all programmes, aligned to demanding gateway timing.



In response to these requirements, Jaguar Land Rover are integrating Altair’s NVH Director into their Vehicle NVH development process. This has enabled the formalisation of model requirements and processes, ensuring that vehicle models are built consistently with standardised load cases and post processing. This allows the reporting of status more efficiently than previously, allowing more time for engineering development and the future ability to stochastically assess the robustness of engineering solutions and likelihood of error states.

Build, Verify & Optimise a Body-in-White Structure in a Working Day
Dr. Tayeb Zeguer, Group Tech Leader APD, Advanced CAE at Jaguar Land Rover presents at the UK Altair Technology Conference 2019. A Design exploration, loadpath studies, material selection and heavy usage of Optimisation are key to the development of a lightweight and efficient Body-In-White (BIW) structure. Nevertheless, the fast pace of vehicle development makes it a challenge to do such CAE work fast enough to drive the design and the decision making. This is why the C2 phase of the Altair C123 process is the ultimate weapon to drive the design in a fast and reliable manner. By using low fidelity models, the C2 phase allows quick iterations, large DOEs and complex optimisation studies to be executed within minutes and have a large impact on design and strategy decisions.



The natural starting point for the C2 process is the supply of a C1 layout model with associated CAD packaging data. However, another entry point is the availability of a high fidelity finite element model from a previous program. The initial activity is the rapid development of a C2 model which can generate a reliable and good quality results. This is the reason why Altair has developed various tools to ease the process of creating “ready to optimise” low fidelity models. Thanks to a highly automated series of tools combined with highly advanced optimisation technology, it is now possible to build, verify and optimise a BIW model for Noise, Vibration and Harshness (NVH) and Crash in a single working day.

Using Advanced Simulation to Design Leading Motorcycles
Rod Giles, Group Manager CAE & CAD presents at the UK ATC 2019. Royal Enfield has and is undergoing a massive transformation, not only in the sales and manufacturing departments, but also in the way the motorcycles are designed and developed. Leading the way in the development of all new motorcycle platforms is the use of advanced Computer Aided Engineering (CAE) tools. At Royal Enfield we use a wide array of different tools and techniques. The primary tool for model preparation and analysis is Altair Hyperworks. Rather than trying to cover the vast range of analyses carried out, today I will concentrate on some examples where advanced techniques have helped the design process including using smooth particle hydrodynamics (SPH) in explicit analysis to evaluate fuel tank integrity, using NVH director to evaluate and improve transfer path analysis (TPA) to aid the rider comfort, using topology optimisation to reduce mass and improve structural performance of engine and chassis components, and using MotionSolve to understand complex mechanism dynamics.

Highly Optimized Passive Lubrication System for an EV Transmission
Presentation by Dr. Milos Stanic, nanoFluidX Product Manager at Altair.



Optimising the rotational losses of an EV transmission is essential to improve range. Whilst bearing and gear losses are well understood, the interaction between rotating components and transmission fluid rarely exploited other than reducing lubricant viscosity. Effective methods for modelling drag and fluid transfer around a transmission have not robustly existed previously.



Converting electrical power into mechanical power to drive a fluid pump is wasteful. However, in tightly packaged EV transmissions where thermal cooling is limited it is essential to manage the lubricant. A novel method for passively moving fluid around an EV transmission with low losses has been developed. The system uses existing components in the gearbox to move fluid in a controlled manner. The cost savings of using this technology can be used directly elsewhere to improve vehicle range.



In order to iterate through potential design solutions a suitable computer based modelling approach had to be developed. A new smoothed particle hydrodynamics approach was created to predict the fluid movement and the drag level on the remaining components. A correlation of this approach was carried out with real world testing to prove its validity.

During his keynote, Prof. Thomke explains why business experimentation is so critical to the management of innovation, underscores the huge potential of simulation (and new digital platforms), and outlines what managers must do to integrate them successfully. Drawing on two decades of research in multiple industries, he provides striking illustrations of how companies execute innovation more effectively.

Overview of MDO & Methodologies for Meeting the Challenges for Efficient MDO Execution
Presentation by Dr. Royston Jones, Executive VP, European Operations & Global CTO at Altair.

As products increase in complexity, design becomes more multi-disciplinary and the requirement to efficiently deploy Multi-Disciplinary Optimization (MDO) becomes a significant design differentiator. Increasingly, industry is successfully performing MDO studies to achieve optimized balanced design allowing trade-offs between mass, performance and even cost.

In order to impact the product development process, MDO results must deliver to project timescales and in order to achieve this, a number of challenges need to be overcome. Typical challenges consist of efficiently performing MDO pre- and post-processing and solution activities. To meet these challenges, Altair has utilized its expertise in model management, large dataflow, job submittal, optimization and visualization, leveraging HyperWorks technologies to create a vertically integrated end-to-end process software tool.

The World is Built on Engineering
Dr. Uwe Schramm and James Dagg, CTOs at Altair, keynote presentation at the 2018 Global ATC in Paris, France.

This presentation will illustrate the power of Altair’s simulation technology through several practical examples applied to some of the most common product development challenges in automotive, aerospace, and other industries.

Starting with simulation in the early phases of concept design, designers can take advantage of CFD simulation to explore and validate how different designs impact the aerodynamic performance of a vehicle. Viewers will be shown how complex, detailed nonlinear airframe simulations can be modeled and performed quickly and accurately. The presenters will also explain how multiphysics problems like e-powertrain development can be solved with a model-based development approach, which considers electrical and electro-magnetic simulation of systems and sub-systems.

Efficient Multidisciplinary Modeling of a Washing Machine Motor Duty Cycle
Presentation by Dr. Martin Ortega, Principal Design Engineer at Mabe.



This work presents a systematic process of the electromagnetic and thermal analysis of a washing machine single-phase capacitor-run induction motor during a full wash cycle. By utilizing an electromagnetic solver and a one-dimensional systems modeler, the designer is able to evaluate the thermal heat rise and power losses of the motor faster, at a limited cost and in a limited time.


Defining Positioning System for Heavy Lift Barge with AcuSolve
Presentation by Pawel Sadowski, Technical Support Manager at DES ART.

Even during building roads your approach may be different from the standard one. The nature often forces engineers to use their creativity and go beyond typical projects. This leads to some unique, futuristic structures or some additional projects that have to be done and at the end are invisible. Our project of heavy lift barge contains in the second group. One part of this project was to proof that positioning system is sufficient to keep right position at the sea even during unfavorable weather conditions. For this purpose we perform numerous CFD analyses using AcuSolve. Computational cases differed in angle of flow, speed of flow and configuration of the barge. As a result of these all analyses defined working area of positioning system.

Thermal and Impact Analysis of a Nuclear Flask Design
Thomas Goulding, Senior Mechanical Engineer at Assystems presents at the UK ATC 2019. Nuclear transport flasks are used to store and transport nuclear waste material. When transported on public roads the flask must fulfil International Atomic Energy Agency (IAEA) test requirements, which are designed to ensure that release of radionuclides is not credible. Whilst on-site, the flask requirements are driven by the Safety Justification which can be quite different to those defined by the IAEA.

A function-led design process was undertaken to fulfil these requirements for an IAEA Type B(M) package. This required a range of drop impact simulations using RADIOSS.

Altair HyperWorks was used as a common enabling tool for the analyses. The tools within HyperWorks were used to perform multi-disciplinary optimisation of the flask, without the need to revisit the Computer-Aided Design (CAD) model. Workable solutions, proven by simulation, were then incorporated into the CAD design. This function-led process was seen to be more efficient than the traditional trial-and-error approach.

HyperMesh was used for mesh creation due to excellent element control and its capability to support a variety of solvers.

The use of HyperCrash (pre-processor), RADIOSS (solver) and HyperView (post-processor) enabled non-linear impact analyses to be performed.


Integration of Optimization into Design with Altair's MDO Offering
CAE has since long been established as the tool for validating and certifying mechanical properties during product development. Simulation-driven design takes simulation and optimization into the creative design process. Primary goal of simulation-driven design is to provide a continuous stream of decision data to support concept design and later product development stages.

Optimization of Spacecraft Metallic Primary Structure with OptiStruct
Spacecraft primary structure is designed to react all the major loads imparted on a spacecraft. Inadequately designed or tested primary structure can result in structure failure during launch and endanger mission success. To maximize the useful payload to orbit, primary structures are typically designed to minimize mass while maximizing strength and stiffness characteristics. Identifying an optimal balance of these three design characteristics can be challenging due to the extensive number of load cases applicable to the primary structure. For this study, multiple finite element models (FEM) are optimized to define a metallic panel capable of reacting launch loads and supporting a large secondary payload mounted to the panel. To react the launch loads, the panel strength margins are evaluated and the secondary payload’s 1st bending mode is maximized to reduce dynamic coupling with the launch vehicle dynamic environment. For the optimization, the mass is constrained to not exceed an available mass budget. The primary structure panel is connected to a generic spacecraft bus representative of a typical Northrop Grumman satellite.

Random Vibration Procedure and Best Practices
In order to evaluate if a design is robust and meets design margins, engineers use a variety of analytical tools. Often a product’s duty cycle is not perfectly characterized but the statistics of a lifetime of excitation are known.
These excitations can cause fatigue when system level dynamics are excited. It is very important to understand how a system responds to these excitations and how natural frequencies interact with each other.
Power spectral density (PSD) analysis, more commonly known as random response analysis, is used to determine stresses and strains in a system that is subjected to random excitations.
