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".

Design for Additive Manufacturing with Topology Optimization
Presentation by Avishai Warszawski, Mechanical Designer at IAI, Israel Aerospace Industries at the ATCx in Israel, Netanya on October 30, 2019.

The goal of this project is to design a lightweight and stiff support bracket for delicate coaxes which are attached to an electronic unit. The machining design of this bracket, although very light in weight, did not provide the required stiffness and was also very expensive to manufacture. The best approach for design was only realized after the AM team was requested to find a solution. Topology optimization with Altair tools was used to define the best shape that provides the best solution. Finally, the bracket was printed in an SLM machine from AlSi10Mg. In the near future it will be qualified by dynamic tests in accordance with the defined environmental loads.

From MBD to FSI Complete firearm development
Presentation by Konstantin Arhiptsov & by Eitan Maler, Simulation Dept. IWI
Israel Weapon Industries (IWI) at the ATCx in Israel, Netanya on October 30, 2019.

These days, in IWI, complete multi physics simulation is an integrated tool in the development of any new product. The motivation is to completely simulate one or two firing cycles as close to reality. First step is the Multi Body Dynamics simulation to check all mechanism are synchronized and work properly. Second is the explicit simulations - calibrating the mechanical properties of the pistol, in that the springs, contacts, materials and gun powder properties based on one firing cycle. The following is to calibrate the Non Rigid Boundary conditions (NRBC’s). This calibration of boundary conditions which are not completely fixed is crucial to understanding the actual strains and stresses on the parts. One of the approaches was to use known data of the stiffness of arm and wrist, implementing this data into a HyperStudy model to compare and calibrate the results based on a slow motion capturing of a real firing. The results are promising, with high accuracy of the behavior compared to a real capturing of the shooting, up to the point of slider getting to the end of its move – where most of the kinetic energy transform into loads on the frame. The following steps will be to calibrate, using the same method, the return of the slider to it’s original position and perform more than one firing cycle.

Dynamical RCS - Helicopters in pulsed Doppler radars image 
Presentation by Tal Oz, Officer, Israeli Air Force.

Many modern radars measure the radial velocity of airborne targets using Doppler shift to distinguish between real targets and clutter (trees, clouds, birds). Radial velocity and Doppler shift are directly related for regular airborne targets such as Boeing 747 but even a standing still helicopter will produce some sort of measurable Doppler shift. It is a computationally difficult task to find the relevant helicopter RCS but a feature provided by Feko, the ""Numerical Green Function"" can dramatically improve computation time of such problems. The lecture will begin with relevant Radar and RCS introduction, some highlights of important Feko features and dynamic RCS results of a CAD model of a helicopter.

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.

Vehicle Concept Design using Ride & Comfort Requirements for Truck & Trailer System Dynamics
Presenter: Kaustubh Deshpande, Chassis Engineer, Nikola Motor Company


This presentation describes Nikola Motor’s progression of design maturity from 1D CAE to 3D CAD/CAE for chassis system engineering work on their electric trucks. This progression spans from Voice of Customer to Functional Requirements to Functional Deployment to Structural Deployment.

Nikola Motor starts with a ‘First Principles’ model of their truck/trailer vehicle dynamics, then they perform system modeling & simulation with Altair Activate using quarter- and half-truck/trailer models. Block diagrams are created using both signal-based blocks and physical-based blocks (with Modelica).

Through this methodical process, Nikola Motor is able to derive more and better insight earlier in their development process regarding important vehicle characteristics for their trucks – ranging from ‘yaw rate of the tractor for loaded vs. unloaded trailer’ to ‘full-trailer load distribution sensitivity due to fifth wheel location’.

Work is in-progress to tighten the connection between their 1D CAE simulations in Altair Activate™ and their 3D CAE multi-body dynamics simulations.

Interactive virtual prototypes allow for human-factors test and measuring system performance in hyper-realistic virtual worksites. Simulation is also being used for AI based perception and motion planning in autonomous systems. Sales and marketing departments are now using interactive simulations and visualization to demonstrate products. The value of simulation is expanding rapidly in OEMs.

CM Labs Simulations has recently partnered with Altair to bring together engineering simulation and interactive real-time systems models to perform all of the above. Validated multibody systems dynamics models from Altair MotionSolve can be used to build interactive models in Vortex Studio and combined with advanced real-time 3d graphics to create immersive live simulations with human interaction. With real-time simulation, it is also possible to connect to interactive control models and system level multidisciplinary simulations with Altair Activate.

The presentation uses a mobile crane model as an example. It will demonstrate the process of translating the engineering models to real-time, creating realistic working scenarios and deploying in immersive simulators for operator in-the-loop testing and system demonstration.

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.

Modelica Library for Real-Time Car Simulator
Presenter: Dario Mangoni, Engineering Professor, University of Parma


In the modern car industry, the advent of hybrid and electric vehicle systems is driving radical changes in the car electronics and software, demanding more and more advanced controlling techniques. Self-stopping, self-starting, ultimately self-driving cars are nowadays possible, because of the multitude of sensors, controller units and actuators making the vehicles “smart”. To simplify and make the interaction between the user and the machine more and more intuitive and user-friendly, a much broader and deeper investigation of different use scenario combined with the human interaction and intervention is critical. In this context, higher-detailed vehicle models are required to provide a valid prototyping tool which can be reliably used to test innovative controlling strategies, such as testing with the Man-In-the-Loop.

The Car Real-Time Modelica library proposed here aims at providing a highly valuable tool for the vehicle control system design and test. The key competitive advantages in this approach are in the Maple model-based compiler for supporting high-level of details modeling; the adoption of the Modelica language which allows a transparent and physical approach to the modeling activities and finally the Activate platform which offers real-time capabilities within an environment meant for the signal-based control design. To graphically validate the library results, a visualization framework for realistic real-time simulations that assures high-fidelity scenario in which to test user experience was also realized.

Multi-body Enhancements & Customer Successes
Presenter: Rajiv Rampalli, Sr VP in HyperWorks Core Development team, Altair


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).


System Simulation for HVAC
Presenter: Christian Kehrer, Altair [on behalf of Oliver Höfert, Simulation Engineer at Kampmann]


The increasing virtualization of engineering methods is inevitable. This also holds true for the design of systems that take care for the thermal well-being of humans, e.g. in buildings. If it comes to simulation of so-called HVAC (heating, ventilation, air conditioning) systems, very often high fidelity approaches like CFD are connected to it. In contrary, this contribution illustrates a 1D modeling approach of a heat exchanger in use of Altair Activate.

The presentation explains the implementation of the NTU (Number of Transfer Units) method in a system simulation environment. This includes a short description of the approach itself as well as its current limits. Based on the implementation of a single cell, differing network configurations for the evaluation of use cases of varying complexity will be shown.

ROMs For Battery Cooling Systems
Presenter: Stefano Benanti, R&D materials engineer, Hutchinson


Battery cooling (BC) systems are frequently composed of several parallel branches, each leading to and away from a series of cooling plates. As a correct flow distribution in each branch and overall pressure drop are a key requirement from every customer, numerical computation is extremely important from the first stages of each project: the number of components and their dimensions have a relevant impact on the total cost and it is thus necessary to quickly provide results already in the Request for Quotation (RFQ) phase.The 3D computation of such cases, albeit feasible, takes a relevant amount of time and makes it more costly (both in terms of computational power and of necessary software licenses) to quickly provide results. The goal is then to develop a quicker method to provide results and allow for the necessary optimization cycles.

Altair Activate® was chosen by Hutchinson to develop a library of ROMs representing different circuit components through which is possible to create 1D models able to respond quickly and precisely to such demands.

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.

The role of finite element analysis in the development and optimization of novel sports head protection
Head health and safety has been an emergent theme within the scientific community, with an emphasis on mild traumatic brain injury. Protective equipment, such as helmets, provide a method of reducing the forces of impact that are delivered to the brain. However, innovation in this field has been limited and up until recently, the prevalent technology in most helmets on the market consisted in foam cushions and/or inflatable bladders. In fact, in 2006, several researchers estimated that improvements in helmet technology would become limited by the inherent properties of foam materials traditionally used in protective equipment. In 2015, VICIS announced a new impact mitigation concept based on buckling a filament structure. The first production helmet, the ZERO1, used a comprehensive suite of physical tests and additive manufacturing to implement a rapid and iterative design process. Finite element modeling (FEM) was introduced during the development of ZERO1, in a way that complimented the established fast-paced protype and test method.

FEM allowed for accurate simulations in a rapid and repeatable method. In addition to the non-linear geometric and material response, the majority of components in the ZER01 are soft bodies that experience large deformation. HyperMesh and Radioss provided the stable platform to evaluate impact performance as well as part durability. This study reviews the role and implementation of FEM in VICIS's second production helmet, the ZERO1-Youth, and the progression from component-level to system-level simulations.

Piloting SimSolid for Fast Directional Feedback to Reduce Product Development Timelines
"The analysis team at CNH is piloting Altair SimSolid™ as a design refinement tool solution for providing fast directional feedback to the engineering team.

CNH has performed some correlation studies against HyperWorks FEA for accuracy, and has established some criteria for identifying the appropriateness of SimSolid in our workflow. It has been determined that good correlation is attainable even with relatively large assemblies. The relative speed in SimSolid vs that of HyperWorks has shown to vary widely from study to study. This presentation shares CNH's experiences and recommendations with this software."

The presentation will illustrate how newly released Altair tools can be used to bridge the gap between Aerodynamics and the Design Studio to understand the performance of ideas as early as the sketch pad, using the skills and resources you already have in house. Altair’s vision for conceptual design in the future will be presented.

Rapid Exploration and Development of Intelligent & Efficient Vehicle Architectures
James Truskin of Fiat Chrysler Automobiles presents Altair's C123 process to create Simplified Loadpath Models (SLMs) for advanced body in white (BIW) design. These concepts provide a highly flexible and rapid platform to explore body structure loadpath alternatives and performance: weight optimization. The C2/SLM modeling process combines higher order Beam and Bush finite elements with coarsened Shell-meshed panels to represent the body structure. FCA US LLC has understood and validated the C2 process for a BIW, and correlated key structural performance metrics to higher order, detailed Finite Element (FE) models. While the benefits of loadpath optimization through Beam element parameter variation is well-documented, and applied extensively for these types of models, this presentation provides a better understanding of the sensitivities and influence of joint stiffnesses on key body structure attributes to promote more intelligent and efficient body structure joint designs.

Presenter: Christian Kehrer, Business Development Manager, Altair


This presentation discusses the multi-disciplinary evaluation of truck platooning, with the lead truck sending out acceleration, braking and steering signals for the following trucks to react accordingly. The benefits address safety requirements, fuel savings, traffic capacity and convenience.

The presentation demonstrates why platooning requires a holistic approach in the sense of connecting different modeling and simulation methods for a virtual evaluation of this system of systems.

Exoskeleton Modeling Using MotionSolve & Activate
Presenter: Nino Michniok, Mechanical Engineering Student, University of Kaiserslautern


The first part of the presentation shows the detailed process of building the multibody system of an actuated exoskeleton in MotionView/MotionSolve (MV/MS). The required movements are transferred to the corresponding joints by “Motions”. By this the exoskeleton can Stand Up, Walk diagonally across the floor and Sit Down. In the second part the “Motions” in MV/MS are replaced by controllers (position control) whichdeliver a certain torque to actuate the exoskeleton. The main topic here is the implementation of the co-simulation between Activate and MV/MS. In the end the presentation gives a quick outlook of similar works at the University of Applied Sciences Kaiserslautern in Germany.

Over the past several years, however, rapidly changing technology has allowed thousands of new, powerful, and inexpensive IoT sensors to hit the market — making it possible to implement smart solutions in small and mid-sized buildings which make up 90% of the commercial building stock globally. Learn more about how Altair’s SmartWorks platform is enabling commercial building owner/operators and service providers to create and deploy smart and connected building solutions to affordably and efficiently collect large data sets on their building assets which can be used downstream to optimize the building’s efficiency.

Data Driven Models for HVAC Load Prediction
Consumers electric bills typically have two primary components: energy charges and demand charges. Demand charges are significantly costlier (10 times on average) than normal energy charges because of the inherent production cost to maintain the demand over a certain limit. This presentation proposes a model which can forecast upcoming demand charge events which in turn can help the consumers in optimizing their energy usages and hence help them avoid going to demand charge band.
