Innovations in a floating production system for optimizing costs

An optimization process using modeFRONTIER is implemented with the aim of optimizing the design of a floating production system with the minimization of installation and operating cost in mind. The hull form was designed using a genetic algorithm, taking into account 7 parameters, and focusing on minimizing steel weight.

Study of the impact of structural parameters on the dynamic response of an electronic fuel injector

The study concentrates on the effects of structural parameters of an electronic fuel injector on its dynamic response. The injector was developed for a marine medium-speed diesel engine. The dynamic response from the start of the control signal to the end of the needle valve closing was investigated. Firstly, a complete and detailed model of the electronic fuel injector was built and integrated into an optimization model, where a MOGA was applied.

How to optimize an external gear pump in highly constrained conditions

The objective of this project was to take a standard series gear pump with a displacement of about 20 cc/rev and to minimize its noise emission, while at the same time maintaining the same level of performance. The optimizer modeFRONTIER and simulator HygeSim are used to find the optimal configurations of the pump model. 

Azimut Benetti propels cruise speed with modeFRONTIER

The Naval Architecture and Marine Engineering Unit (DITEN Department) of Genoa University work jointly with DETRA Custom Propellers and Azimut Benetti’s R&D Centre, using modeFRONTIER to optimize the design of a custom propeller for a high-speed Azimut Benetti 95 RPH yacht.

 

Advanced Predictive Diesel Combustion Simulation Using Turbulence Model and Stochastic Reactor Model

This work studies the modeling of turbulence time-scales in diesel engines within a 0D model framework. The goal is to see its effect on combustion and emission formation taking into consideration different operating conditions. The combustion is described using the pdf based DI-SRM. Optimization was run using modeFRONTIER.

ESTECO webinar recording | A CAD-Mesh mixed approach to enhance shape optimization capabilities

In this joint webinar, ESTECO and RBF Morph present an innovative CAD-Mesh mixed approach to enhance shape optimization capabilities. Riccardo Cenni from SACMI describes how engineers at SACMI Ceramic Engineering Department leveraged modeFRONTIER, RBF Morph and ANSYS Workbench to develop an hybrid methodology combining CAD and mesh based approach overtaking the limits of the shape optimization based on the single disciplines. 

TOWARDS A METHODOLOGY FOR MULTIDISCIPLINARY DESIGN OPTIMIZATION

The presented research proposes an MDO-based methodology for design of high-performing haptic devices. Input data are modeled in Matlab and Creo Element. By utilizing the ModeFRONTIER software tool, these models are integrated in the MOGA-based automatic optimization process. At the end, sets of Pareto optimal solutions that fulfill all constraints are generated and stored for further analysis. 

Multi-objective optimization of a bottoming Organic Rankine Cycle (ORC) of gasoline engine using swash-plate expander

In this paper, a thermo-economic model of the ORC system coupled to a gasoline engine is presented. This model is based on energy balances and economic criteria of the different components of the ORC system. The main objective of this work is to evaluate this thermo-economic model as a tool to optimize a multiobjective problem using a Genetic Algorithm.

Modelling and Multi-objective Optimisation of the VHP Pouch Packaging Sterilisation Process

This paper aims to optimize the pouch packaging sterilization process used in aseptic technology. The study is made of two parts: first the modeling and fluid dynamics simulation of the sterilization process on the pouch with a subsequent experimental validation, and then the multiobjective process optimization, with the aim of finding
the most suitable system configuration using modeFRONTIER.

Modeling and multi objective optimization of closed loop supply chains

This paper investigates an optimization methodology of an asset management process in a real closed-loop supply chain (CLSC). The model is reproduced on a simulator and exploited for multi-objective optimization purposes, supported by the commercial software ModeFRONTIER.
