Performance Evaluation, Scalability Analysis, and Optimization Tuning of Altair HyperWorks on a Modern HPC Compute Cluster
Engineers from wide ranges of industries face ever increasing needs for complex, realistic models to analyze the most challenging industrial problems; AcuSolve is designed to tackle these finite element-based Computational Fluid Dynamics (CFD) simulations with superior robustness, speed, and accuracy. AcuSolve simulations are designed to carry out on large-scale computational systems effectively. The breakthrough in HPC parallel computing that allows such complex analyses to be performed that generate the high-quality results, while reducing simulation time from days to just hours. Behind this type of computational improvement that makes AcuSolve perform, it involves complex calculations and data exchanges among computational systems. The more complex simulations are being performed, the higher demands from the cluster performance are. In this analysis, the HPC Advisory Council has performed a deep investigation and profiling for the AcuSolve CFD solver to evaluate its performance and scaling capabilities and to explore potential optimizations. This study presents the optimization techniques and networking profiling results to further understand AcuSolve dependencies on the CPUs, communication networks, IO subsystems and the underlying hardware. The paper will review the effects by comparing various hardware using different simulation models.


Structural Component Design Optimization for Additive Manufacture Structural Component Design Optimization for Additive Manufacture Learn More
Structural Component Design Optimization for Additive Manufacture
Additive manufacturing (AM) technology enables the possibility of realizing highly efficient, optimized structural components with configurations not achievable using conventional manufacturing methods. The Altair and Solid Thinking toolsets provide advanced capabilities to design structural topologies to minimize weight and maximize other performance criteria. However, conventional manufacturing processes require application of design constraints, such as directional access for machining, in the optimization that limit the structural efficiency of the resulting design. AM can remove many of these constraints to allow for more efficient configurations under the applied loading conditions. Case studies show the potential to reduce weight up to 30% for components with applied bending and torsional loads by allowing increased complexity configurations that could only be manufactured additively.

Teaching Aerospace Design Optimization
Engineers develop design and analysis skills through application of principles, methods, and tools to the solution of complex, often ill-defined problems. Engineering training that focuses on simple, focused component-level applications teaches some portion of the skills needed to execute real world problems but is incomplete. Altair has experience both deep and broad in applying optimization technologies and has developed a training curriculum aiming to teach engineers more comprehensive design optimization skills and knowledge in aerospace applications. The Altair Aerospace Optimization Academy has been developed as a series of online modules to develop deep design and optimization knowledge and skills in engineers that have basic structural analysis and finite element experience. The training curriculum leads students through complete design cycles using Altair’s advanced optimization technologies and explores the different approaches that engineers can use to develop aerospace designs for a variety of metallic and composite components and configurations.

By using the ARD tool, Mahle was able to reduce the lead time for a report from over 4 hours down to less than 1 hour.

Forming Simulation of Woven Composite Fibers and Its Influence on Crash Performance Forming Simulation of Woven Composite Fibers and Its Influence on Crash Performance Learn More
Forming Simulation of Woven Composite Fibers and Its Influence on Crash Performance
The automotive industry, in its constant quest for weight reduction, is increasingly considering composite materials as a substitute for sheet metal components to meet future fuel consumption standards. However, composite forming processes are expensive and difficult to control because of the complexity of the material behavior with fiber and matrix layers or plies and its dependency on many parameters, such as non-linearity of tensile stiffness, effect of shear rate, temperature and friction. Hence, numerical simulation could be a viable approach to predict material behavior during composite forming. The objective of this study is to highlight capabilities of RADIOSS™ to simulate forming simulation of composite plies made from woven fibers, each ply modeled as a layer of woven fibers along two directions of anisotropy, warp and weft. For validation the well-known double dome model published in NUMISHEET’05 proceedings is used. The compared result is the shear angle after stamping that is, the final angle between warp and weft fibers, at several prescribed points on the ply. The variation of this angle has a strong impact on material characteristics which severely deteriorates when a critical value is reached. Hence, a study on crash simulations is performed, after mapping fibers angles from stamping simulation.

An Automated Head Impact Process Setup for Automobile Instrument Panel (IP) Application
FMVSS 201 procedure originally rolled out in 1968 by Federal Motor Vehicle Safety Administration to protect the automobile occupants from fatal injury during the crash. Since the beginning of the law, the automobile interior safety has become considerably more challenging for manufacturer to meet FMVSS 201 standard criteria. During the course of instrument panels (IP) development, engineers are heavily relied on computer simulation to optimize the design for a more robust design. Based on FMVSS 201, there are an infinite number of target points on the instrument panels that must be tested for head impact performance. Therefore, this becomes not only costly but it is impossible for the manufacturer to test all possible target points using the current conventional process.

A Multifunctional Aerospace Smart Skin Emerges from Computational Models and Physical Experiments
The capability to assess the current or future state of the health of an aircraft to improve safety, availability, and reliability while reducing maintenance costs has been a continuous goal for decades. Many companies, government agencies, and academic institutions have become interested in Integrated Vehicle Health Management (IVHM) and a growing effort of research into “smart” vehicle sensing systems has emerged. Methods to detect damage to aircraft materials and structures have historically relied on visual inspection during pre-flight or post-flight operations by flight and ground crews. More quantitative non-destructive investigations with various instruments and sensors have traditionally been performed when the aircraft is out of operational service during major scheduled maintenance. Through the use of reliable sensors coupled with data monitoring, data mining, and data analysis techniques, the health state of a vehicle can be detected in-situ.

Evolving Trends in the Structural Optimization of Aircraft Gas Turbine Engines
Brian Cottrell, Chief Engineer of Structures, Honeywell Aerospace

The history of aircraft gas turbine engine design generally has not included significant optimization of the structural layout of engines. This optimization gap has been driven by the pace of engine layout during the concept development phase and by the extreme complexity of the problem. Therefore the initial selection of the structural system concept has tended to be anchored in experience and in simple parametric trade studies seeking to provide a sound configuration from the perspectives of strength, weight, cost, and modularity.
