Fluid mechanics simulation is a critical tool for late-stage failure risk mitigation, as well as a driver of design insights throughout the product development process. Used across all levels of product design and validation, from design engineers seeking to understand fluid and thermal effects on a design proposal to analysts performing advanced aerodynamic modeling, Computational Fluid Dynamics (CFD) serves a broad array of applications and a range of users with varied levels of expertise. The sometimes complex and computationally intensive nature of CFD necessitates careful consideration of the software and hardware investments required to produce accurate solutions and scale them at the speed of a company’s development process.

This presentation shows how advanced simulation technology can provide a cost effective way to minimizing the risk breaching noise regulations. Often the issue is only found out in a prototype testing scenario, bench test results can give misleading information as acoustic character of a rotating component will change in an installed condition. Altair CFD brings a solution to the market for installed fan acoustics by directly calculating the convective field, this virtual method can significantly reduce risk of failure leading to development cost savings and mitigation of timeline overshoot.

Overview of Materials, Environments, and Darkroom.

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.

Altair was founded in 1985 with a vision to use simulation to drive design and decision-making. Through the years simulation has evolved from the back end of the design process to the front — and today's cloud infrastructure opens up new possibilities to solve problems of unlimited size.

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.

Presentation by Jean Thiriet, Thea Render.

Within the course of an architectural project, the meeting of client objectives, site constraints and the architect's ideas gradually shapes the future building.

At the heart of this creative process, a virtual model is used to bring together different elements of the reflection (handmade sketches, CAD drafts, etc.) into a coherent object. This model is refined many times as the project evolves, and is ultimately used as a support to create accurate images of it, at each step of its development.

Based on a set of projects from the Parisian architectural studio DTACC, this presentation will show how the Thea Render software occupies a central place, in both the design process and the communication phase, by allowing fast and precise photo-realistic representations of virtual models.

In this white paper, we present the innovative commercial GPU-based Computational Fluid Dynamics (CFD) solver Altair ultraFluidX. This work features simulations of the DrivAer model, a generic, publicly available vehicle geometry that was developed by the Chair of Aerodynamics and Fluid Mechanics at the Technical University of Munich and which is widely used for testing and validation purposes. The DrivAer model features rear end, underbody designs, and underhood flow. This model was then used to perform both wind tunnel tests and numerical simulations of the 40% scale open cooling geometry using perforated aluminum sheets with different opening ratios to mimic different radiator properties. Within, we will compare some of the results from these wind tunnel tests with numerical results obtained with Altair ultraFluidX.

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.
