Using HyperWorks to Generate Electrically Large Surface Meshes for Radar Cross Section or Antenna Placement Simulation

Radar Cross Section (RCS) and installed antenna placement are important parameters for aircraft designs. RCS is a measure of how detectable an object, such as an aircraft, is with radar.

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.

HyperWorks Improves Development Processes in Automotive Industry

In 2008 PWO Germany (Progress-Werk Oberkirch AG) had to develop and produce a new steel made automotive cross car beam (CCB) for the dash board of a new car. PWO received the CAD model, the design space definition and other pre-defined standards of the component from the customer and developed and produced the fitting cross beam based on this information. PWO used the HyperWorks Suite to develop the component. HyperMesh was used to transfer the CAD model into a FEA model, which was then used to run dedicated analysis and simulation tasks. To fulfill the requirements for crash and modal analysis, the company used OptiStruct to optimize the component, RADIOSS and other external solver to run the calculations and HyperView for the post processing. HyperForm was used to check the production feasibility of the individual components and for metal forming simulation tasks. It was important for PWO to have a software suite available that could cover all simulation tasks within one graphical user interface and licensing system.

FEKO: Electromagnetic and Thermal Analysis of a Human-Body Model with Implant in MRI

Image quality in magnetic resonance imaging (MRI) depends on good radio-frequency (RF) coil design. Such coils can be designed efficiently in FEKO thanks to the simulation methods the tool offers.

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.

HyperWorks 12.0 Rollout Webinar Series Crash Modeling and Analysis (HyperCrash)

Model-Based Development with Altair

Today, most products are a combination of mechanical, electrical/electronic, and controls/embedded software. In order to manage product complexity and ensure innovation, organizations turn to a model-based development approach for concept studies, control design, multi-domain system simulation and optimization. Altair recently released a unified solution (solidThinking Compose, Activate and Embed) for math and system modeling. Watch this on-demand webinar to learn more.
