Leveraging HyperWorks for Advanced Human Body Models in Vehicle Crash Simulations - Altair Industrial IoT Case Study
Leveraging HyperWorks for Advanced Human Body Models in Vehicle Crash Simulations
Wake Forest Baptist Medical Center, a leading research university in biomedical sciences and bioengineering, was tasked with developing highly detailed, finite-element human body models for vehicle crash simulation. The Center of Injury Biomechanics (CIB) at the university was to investigate injury mechanisms following trauma resulting from vehicle crashes to develop a greater understanding of human tolerance to injury and to engineer enhanced safety countermeasures. The challenge was to mathematically quantify fundamental human body organs, skeletal members, and body extremities that are subject to trauma. The resulting medical image data had to accurately represent a range of vehicle occupants: adults (male & female), children (3-6 years old), and infants. The human body data then had to be discretized to generate accurate finite element (FE) models of the varied human body systems. These models then had to be integrated to formulate a model of the entire human body, which then had to be validated in vehicle crashworthiness simulations with occupant and pedestrian impact conditions.

Structural Optimization of Concrete Shells in Seismic Areas: A Case Study - Altair Industrial IoT Case Study
Structural Optimization of Concrete Shells in Seismic Areas: A Case Study
The Form Finding Lab at Princeton University was faced with the challenge of designing expressive structures that can safely be employed in seismic areas. The focus was on shell structures, which are thin, curved, and typically large span structures made out of a wide range of materials ranging from steel and glass, to concrete and even bricks or mud. These structures have empirically shown their excellent performance during earthquakes, as exemplified by the undamaged survival of the shells by the acclaimed shell builder Félix Candela during the great 1985 Mexico City earthquake. However, powerful computational tools were needed to analyze the behavior of these structures under earthquake loading. The researchers needed to investigate the effects of a shell’s shape on a buildings’ performance during an earthquake and to simulate the influence of thickness variations on the response due to shaking caused by the earthquake.

HyperMesh and Custom Export Template Streamline CFD Analysis in Research Projects at Arizona State University
The Integrative Simulations & Computational Fluids Lab researchers at the School for Engineering of Matter Transport and Energy (SEMTE) at Arizona State University (ASU) were faced with the challenge of using the commercial code HyperMesh as a general preprocessor to mesh complex geometries for use with the spectral element CFD code Nek5000. The Nek5000 code requires 3D hexahedral elements, which posed a difficulty as most CFD tools use tetrahedral meshes that are easier to generate for conventional geometries. The researchers wanted to benefit from the rich functionality of advanced meshing tools like HyperMesh, capable of producing high-quality hexahedral meshes, while using the Nek5000 solver code. Before the project started, the researchers had no general process for meshing in place. Most of the meshing was handled with custom-made tools that were developed 15-20 years ago and have seen minimal updates since that time. Other users created their own meshing tool for specific problems in software such as MatLab.

The SKA Radio Telescope: Leveraging IoT for a Better Understanding of the Universe - Altair Industrial IoT Case Study
The SKA Radio Telescope: Leveraging IoT for a Better Understanding of the Universe
The Square Kilometer Array (SKA) project, led by the SKA Organization from Jodrell Bank Observatory in the UK, aims to challenge Einstein’s seminal theory of relativity, study the formation of the first stars and galaxies, explore dark energy and vast magnetic fields in the cosmos, and answer the age-old question, 'Are we alone in the Universe?' The SKA will be a collection of various types of antennas, including large dish reflectors and aperture antennas, spread over large distances and working together as an interferometric array. The SKA will be 10,000 times faster and 50 times more sensitive than any existing radio telescope. However, the proximity of adjacent antennas and other systems can result in unwanted inter-coupling, even from low-level emissions, due to currents on cables. This inter-coupling needs to be minimized, which requires identifying the coupling mechanisms and applying measures to improve isolation. On-site radio frequency (RF) coupling investigations are required, but they can only be done after installation. During the design, planning, and installation stages, characterization of the electromagnetic (EM) environment has to be done on scale models and through simulations.

Improved Patient Knee Flexure Post Total Knee Replacement Surgery through Computational Analysis - Altair Industrial IoT Case Study
Improved Patient Knee Flexure Post Total Knee Replacement Surgery through Computational Analysis
Anterior knee pain is a significant complication following total knee arthroplasty (TKA) surgery. The inability to freely extend or flex the knee significantly impacts patients' daily activities such as walking, lifting, and rising from a chair. This knee movement inability is one of the most common indications of needed TKA procedure revisions. The challenge of this study was to quantitatively evaluate the effect of the patellar button thickness on the variation of the quadriceps tendon force during knee joint flexion/extension using computational analysis. A reduction in the force variation is directly related to the mitigation of anterior knee pain following TKA surgery. Poor sizing during surgery of the patellar knee component – a “button-like” element that increases the mechanical advantage of the extension force – was identified as a key issue.
