Ultra-Fast High-Fidelity Computational Fluid Dynamics on GPUs for Automotive Aerodynamics
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.

Tanker Truck Sloshing Simulation Using Bi-directionally Coupled CFD and Multi-Body Dynamics Solvers
In this work, the multi-disciplinary problem arising from fluid sloshing within a partially filled
tanker truck undergoing lateral acceleration is investigated through the use of multiphysics
coupling between a computational fluid dynamics (CFD) solver and a multi-body dynamics
(MBD) solver. This application represents a challenging test case for simulation technology
within the design of commercial vehicles and is intended to demonstrate a novel approach
in the field of computer aided engineering.

Optimizing Cooling Passages in Turbine Blades
Turbine blades have internal passages that provide cooling during operation in a high
temperature engine. The design of the cooling passages is critical to achieve near uniform
temperature of the blade during operation. The temperature of the blade is dependent on the thermal properties of the blade material as well as the fluid dynamics of the air circulating in the cooling passages. Computational optimization methods have successfully been applied to design lighter and more efficient structures for many aerospace structures. An extension of these techniques is now applied to guiding the thermal design of a turbine blade by designing the optimal cooling passage layout. Optimization methods will be applied to determine the optimum pattern of the cooling passages and then to optimize the size of the individual cooling passages. The goal is to produce a more thermally efficient turbine blade design that will produce blades with longer lives and better performance.

Improving the Design of Subsea Riser Systems: A Cray-Altair Solution for Improved Oil & Gas Component Engineering
With Cray and Altair, engineers have the computational systems they need to perform advanced subsea computational fluid dynamics (CFD) analysis with better speed, scalability, and accuracy. With Altair’s AcuSolve CFD solver running on Cray XC supercomputer systems, operators and engineers responsible for riser system design and analysis can increase component life, reduce uncertainty, and improve the overall safety of their ultra-deep-water systems while still meeting demanding development schedules.

より高機能、より安全な容器を求めて、これまで独立に扱われてきた容器内の流体現象と容器の変形応答を同時に扱う流体・構造相関解析(FSI: Fluid-Structure Interaction)への関心は徐々に高まってきている。そこで、本論分では、FSIの基礎となる概念をまとめた上で、四つの流体・構造相関(構造・流体共に既知FSI、剛体構造変形FSI、線形弾性構造変形FSI)解析を示し、超弾性体構成則ALE(Arbitrary Lagrangian Eulerian)を用いた容器内の流体・構造相関の現状と可能性を示した。

Cobot, the Collaborative Robot - Get Ready for Industry 4.0
Development tools and methods, such as simulation, are increasingly important to face and address the pressure of innovation. As an example, for successful new design methods and to show how simulation tools are used, Altair developed a virtual demonstrator based on a cobot application. This complex machine interacts with a human operator as the ultimate smart manufacturing equipment - to show how challenges in modern product design can be overcome.
