  • Design Space Exploration

    When defining an engineering problem and choosing the variables, the region of interest called Design Space is framed. DOE techniques allow for the exploration of the design space by considering all variables simultaneously and predicting the system's response over a wide range of values.

  • A modular framework for the analysis and optimization of power generation systems with CCS

    Developing technologies to reduce emissions from these sources is essential for controlling atmospheric levels of CO2 because of the widespread reliance on coal as an inexpensive and abundant energy source. This framework provides the means to link the various modules together in order to provide a holistic, systems perspective of plant wide operations. Results of analyses and optimization scenarios performed with the framework are also presented.

  • Rooftop photovoltaic (PV) systems for industrial halls - achieving economic benefit via lowering energy demand

    Industrial halls are characterized by their relatively high roof-to-floor ratio, which facilitates ready deployment of renewable energy generation, such as photovoltaic (PV) systems, on the rooftop. This paper performs a cost–benefit analysis in which the monetary return due to electricity generation of PV system is stacked against the annualized cost of the PV system investment.

  • Advanced numerical optimization methods in the rapid product development process of diesel engines

    BMW leveraged modeFRONTIER to optimize the fatigue life of a diesel engine crankcase and gasket. The objectives were to maximize safety factors at the inter-cylinder walls, while maximizing the minimum bead pressure during the low temperature phases of combustion.

  • Maserati car body optimization

    The object of the analysis is a 3D car body of  a Maserati model. Its aim is related to achieve a complete knowledge about the static and dynamic behavior of the car body in its working conditions. The entire design chain exploration was managed by the multi-objective design environment tool modeFRONTIER, which allows a fast search of the input parameters and the objective functions.

  • Effect of acceleration on optimization of Adidas Bounce shoes

    The aim of this paper was to investigate whether the optimum solution changed if the runner accelerated during a stride. The simulations showed that there is very little change in optimum design angle.

  • Automotive Aerodynamic Design Exploration Employing New Optimization Methodology Based on CFD

    In the past few decades, a number of environmentally friendly technologies in the automotive industry have been developed. Automotive styling is also regarded as an important factor in resolving environmental issues by reducing drag force, which results in high fuel efficiency. This paper demonstrates an efficient automotive aerodynamic optimization process and automatic system based on CFD.

  • A method for selecting surrogate models in crashworthiness optimization

    In past decades the simulation results of vehicle impacts have reached high confidence levels. However, impact simulation remains computationally expensive, even though it is commonly used. Surrogate model or response surface based design optimization has been widely adopted as a common process in automotive industry and high fidelity models are often required.

  • Noise Sensitivity Characterization in the Context of the Environmental Design Space

    The international aviation community has grown increasingly interested in the environmental impacts associated with aircraft noise and emissions. Aircraft noise is one of the most significant environmental impacts of aviation, and it is the most common source of complaints from communities, particularly those in close proximity to airports.
