  • Enhancing the efficiency of a Solar Domestic Hot Water (SDHW) system with modeFRONTIER

    Energy consumption for building cooling and heating can add up to 30% of total energy used. With energy standards on the rise, such as the EU’s requirement for renewable energy sources, new technologies have to rise to the challenge. Solar systems and an energy storage system within water tanks could be the answer.

  • Pressure drop reduction in cyclone separator for natural gas by means of design geometry optimization

    This study was based on optimization processes using genetic algorithm MOGA-II in modeFRONTIER and 3D CFD simulations. The focus was on improving design of a cyclone separator for natural gas in order to minimize pressure drop that will increase efficiency.

  • Material Modelling at Volvo Cars, Mapturing Set of Stress-strain Curves for Efficient Reuse

    Capturing data on variation in material quality and the correlations in material property is key to predict material failures and allow for model reuse. Material properties of the rear components of a Volvo car are analyzed from a safety perspective, to improve the energy absorption capability of the bumper and prevent components’ replacement.

  • Meta-Models application on bumper crash design optimization developed with modeFRONTIER

    The challenge of this presentation is the optimization of a bumper during a frontal crash situation. During the optimization six parameters were used in order to optimize the bumper by reducing mass and minimizing force. The optimization comprised three steps that go from geometry design to physical behavior simulation.

  • Multi-level approaches for optimal system design in railway applications

    The focus of this thesis is centered on the optimal design of complex systems. Two main optimization approaches are addressed in this work: the metamodel‐based design optimization and the decomposition‐based complex systems optimal design.

  • A CAE based procedure to predict the low velocity impact response of a composite CAI specimen

    In this case, modeFRONTIER was coupled with an LS-DYNA FE model in order to simulate the impact low velocity impact on composite plate.

  • Parameterization and Multiobjective Optimization

    The main goal of this paper is to show the way in which single and multi-objective optimization can be implemented to improve new products. The author found an optimal strategy for model parameterization of a control arm complying with four criteria and parameterized it  performing automatic and manual optimization to verify the criteria to comply with were met. The overall goal is to reduce weight by 10% the control arm while maintaining the stiffness

  • Finite element reconstruction of real world aortic injury in near-side lateral automotive crashes with conceptual countermeasures

    Traumatic rupture of the aorta (TRA) remains the second most common cause of death associated with motor vehicle crashes after brain injury. On an average, nearly 8,000 people die annually in the United States due to blunt injury to the aorta. It is observed that more than 80% of occupants who suffer an aortic injury die at the scene due to exsanguination into the chest. With the advent of more accurate and established human body finite element (FE) models, FE crash reconstruction methods may become a valuable tool when assessing crash scenarios and occupant injury mechanisms. The current study is divided into five main aims, near side left lateral real world finite element reconstructions, sensitivity study, thresholds for TRA, aorta mechanics in racing crashes and conceptual countermeasures. In the first study eight nearside left lateral impacts, in which a TRA occurred, were reconstructed using a combination of real world crash data reported in the Crash Injury Research and Engineering.

  • Vehicle Aerodynamic Shape Optimization

    Recent advances in morphing, simulation, and optimization technologies have enabled analytically driven aerodynamic shape optimization to become a reality. This paper will discuss the integration of these technologies into a single process which enables the aerodynamicist to optimize vehicle shape as well as gain a much deeper understanding of the design space around a given exterior theme.
