CFD Modeling and Visualization with HyperWorks CFD
Computational Fluid Dynamics (CFD) has long been regarded as an "expert" tool that requires specialized skill sets to apply properly.
Altair for Fluids and Thermal Applications
From detailed component analysis to full systems performance, Altair provides a range of scalable solvers and robust pre- and post-processing software for CFD.
Accelerate Decision Making with GPUs
Harnessing the computational capabilities of the graphics processing unit (GPU) is one of the cornerstones of Altair's mission to empower its customers. First and foremost, utilizing GPUs to accelerate numerical simulation delivers significant increases in speed and therefore, throughput. That means more opportunities to explore and fine-tune designs, faster decision-making based on more accurate results, and consequently the prospect of considerable reductions in time to market. In addition, creativity is enhanced, with more vivid, realistic and accurate rendering and visualization put within easier reach.

Altair's Vision for Conceptual Design in Automotive
Imagine being able to bridge the gap between aerodynamics and the design studio to understand the performance of vehicle design ideas as early as the sketch pad, using the skills and resources you already have in-house.
In this two-minute video Paul Steward discusses Altair’s vision for collaboration between the design studio and aerodynamics.
CFD Simulation for Electric Vehicle Powertrain Development
Gareth Lee, Senior CFD Specialist at Altair presents at the 2019 UK e-Mobility Seminar. How multiphase SPH can support cooling and lubrication system development. Improving powertrain efficiency and thermal management for better EV performance.
Optimizing Powertrain Efficiency and Thermal Management for Improved Vehicle Performance and Energy Efficiency
This presentation focuses on presenting a synergy of different simulation methods and tools towards the accurate prediction of power losses, oil distribution and thermal effects focusing on an automotive and aerospace gearbox example. A number of different approaches are described, including CFD, gear design, bearing design and selection and oil selection, with the aim of maximizing efficiency and ensuring adequate lubrication of critical components and cooling of the powertrain components (e-motor and the associated gearbox)
Altair HyperWorks Brochure
Altair HyperWorks is the most comprehensive, open architecture CAE simulation platform in the industry, offering the best technologies to design and optimize high performance, weight efficient and innovative products.
Traction-based, patented NuVinci® transmission is a continuously variable planetary (CVP) technology enabling performance and efficiency improvements for machines that use an engine, pump, motor, or geared transmission systems. Fallbrook Technologies has been working on improving oil flow inside the NuVinci products as it affects the transmission’s efficiency, durability, power, capacity, and cost.

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.

Developing the Electric Drivetrain of Tomorrow - How Numerical Tools can Support Cooling and Lubrication System Development
Presentation by Johannes Winklinger, Energy & Fluid Expert at Magna Powertrain.
We are right at the beginning of the new mobility era with deep impact on the architecture of cars. Hybridization and electrification are the dominating topics in the automobile industry and consequently the powertrain of cars comes into the focus. However, the development of smart and efficient drive assemblies is challenging due to different and increasing demands such as legal restrictions. Numerical simulations can provide profitable support in the development of such components, especially when they are adopted during the early stages of the design process.

The Three-Click Workflow of nanoFluidX, HyperMesh, and SimLab
The webinar will begin by presenting FluiDyna GmbH and by giving a short introduction to the nanoFluidX (nFX) code. After that the attendees will get a more detailed description of the work flow, emphasizing the ultra-simple pre-processing capabilities of the HyperMesh 14.0.110 and upcoming SimLab 14.2, which allow particle generation with literally three clicks per element. Some details about the solver will also be presented, particularly pointing out the speed up the customer potentially gains in turn-around time for oiling simulations by using nFX on GPU’s. We shall also present the new ParaView 5.0.1 with special SPH features, as well as FieldView version (which should show up by the webinar). Finally, summary and licensing details will be provided for nFX.
