MODELLING AND SIMULATION


the industrial world covers the mobility sectors (automotive, rail, aviation, naval) and all the industrial sectors that use numerical simulation as a key element in their workflow. The activity of Cimes revolves around two main offers: a ‘services’ offer, including engineering and testing services, through which Cimes integrates the product development cycle of its customers; and a ‘products’ offer with the distribution of Altair HyperWorks and Magna Femfat (fatigue analysis). With a strong partnership with software companies such as Altair and Magna, Cimes will be at ATC to present CAE workflows using HyperWorks and Femfat. www.cimesfrance.com


alternatives and their impact on the sound and vibration of a vehicle can be experienced, understood and communicated, ensuring decisions can be made quickly and with confidence. The NVH Simulator technology comprises desktop simulators, full-vehicle simulators with vibration, in-vehicle sound enhancement, sound design for electric vehicles, as well as the Insight+ product available through the Altair Partner Alliance programme. Conference attendees will be able to drive NVH Simulator virtual prototypes created from a combination of CAE data and measurement- based data for a realistic and immersive driving experience. www.bksv.com


Cimes is an engineering company focused on multiphysic numerical simulation, with a specific know- how in HPC. Cimes has two locations: Lyon and Valenciennes (where there is a laboratory for the characterisation of metallic and non-metallic materials, as well as test benches). With more than 25 years of


experience, Cimes’ know-how in www.scientific-computing.com | @scwmagazine August/September 2018 Scientific Computing World 31


Femfat is a finite element solution for fatigue analysis. Results can be achieved from time and frequency domain for high- and low-cycle fatigue. A high variety on modules enables every engineer to configure the software package for his needs individually. Developments from well-known institutes and guidelines are taken into account and modified to fit the assessment method in Femfat. Additionally, it’s based on in-house developments resulting from project works with global customers and measurements and research from ECS (Engineering Center Steyr). The analysis method is a mixture from local stress concept, structural stress concept and


using influence parameters to consider results from high- end simulation techniques. Manufacturing processes like sand castings, die castings, metal forming, stamping and complex material models from laminates or shortfibre-reinforced plastics are taking into account for higher accuracy in fatigue results. Mean stress correction and plasticity in frequency domain are unique capabilities of Femfat. https://femfat.magna.com/


GeonX, acquired by GE Additive Manufacturing in November 2017, will present its solution Virfac FSW at the Altair Technology Conference in Paris. Virfac FSW allows the user to parametrise a thermo-mechanical model,


shoulder and the material to be welded. By the simulation, the engineer is able to customise every process parameter to perform any ‘what if’ scenario they want to try. Using Virfac allows engineers to save time, money, and parametrise the process to obtain the best part possible, in terms of its reliability and life durability. www.geonx.com


HBM Prenscia, developer of innovative concepts and software solutions for understanding reliability, availability, maintainability, safety, durability and performance, will showcase nCode DesignLife for HyperWorks at the 2018 Altair Technology Conference in Paris. Available through the Altair Partner Alliance, nCode DesignLife is a complete fatigue solution that uses leading FE results to identify critical locations and calculate fatigue lives in the time and frequency domains; from high to low cycle, uniaxial to multiaxial, crack initiation to crack growth. It offers advanced capabilities


which aims to predict temperature contours in the welded zone, power dissipation, and the sliding ratio on the interface between the shoulder and the workpiece. The analysis of results


concerning the contact conditions provides interesting data about the evolution of the relative sliding between the


Granta Design are the materials information technology experts who help engineering enterprises meet challenges such as sustainability, lightweighting and emissions reduction, time- to-market and compliance. GRANTA MI is the industry standard for the capture and management of materials data, ensuring traceability, and empowering product design and analysis. Supporting the development of robust materials models for use in simulation, it delivers materials input data where it’s needed to enable accurate simulation,


for vibration fatigue, correlation, stress-life, strain-life, spot welds and seam welds. Even the largest finite element simulations can be processed in batch mode, enabling users to rapidly solve jobs by using the combined processors of many machines. This provides APA users with an unparalleled combination


g


including through direct integration with Abaqus/CAE, ANSYS, and Hypermesh. The CES Selector software, available via the Altair APA programme, supports smart materials choices – for example, to ensure that detailed simulation focuses on the best candidate material. www.grantadesign.com
