Optimization of a Boomerang shape using modeFRONTIER

Achieving best performances for a product need first of all to define the metrics of the performances and design options. Once these are clear modeRONTIER can drive the simulation software to high end result. A boomerang is a flying object quite simple in shape but challenging in the physics...

Bombardier uses modeFRONTIER to optimize high-speed trains

Bombardier uses modeFRONTIER to optimize high-speed trains for drag reduction and improvement of cross-wind stability. In recent years, the German and Swedish based company has turned to modeFRONTIER to drive the design simulations, in order to try to achieve improved greater drag reduction, increased speed with lower traction power and increased cross wind stability.

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.

Automatic calibration of internal combustion engine parameters 3-axis

The main purpose of the collaboration between Alma Automotive and ESTECO is the implementation of a demonstrator able to highlight the added-value given by coupling National Instruments devices with modeFRONTIER framework, while exploiting specific applications developed by Alma Automotive for the engine set-up.

CFD optimization for GDI spray model tuning and enhancement of engine performance

Coupling a 3D Computational Fluid Dynamics (CFD) tool with a rigorous method of decision making is becoming indispensable in the design process of complex systems, as internal combustion engines. CFD based optimization (CFD-O) is here carried out on a single cylinder, four-valve, four-stroke gasoline direct injection (GDI) engine, to enhance mixture formation under stratified charge operation, hence to choose between the single or double injection strategy maximizing the engine power output.

Fatigue Assessment of Panaro Bridge

In this paper, preliminary studies performed on the Italian case study, the Panaro Bridge, are reported. In particular, results of the standard fatigue assessment according to Eurocode rules were compared with the actual fatigue damages occurred to deck secondary components to obtain a preliminary critical review of adopted fatigue assessment methodologies.

Strength Improvement to Composite T-Joints under Bending through Bio-inspired Design

This paper shows that a bio-inspired design methodology is an effective method to strengthen composite T-joints under bending loading, whose ply angles were tailored using an optimisation program mimicking the evolutionary process of adaptive growth.

Prestress optimization of hybrid tensile structures

This paper deals with cable domes design and study the role of the cable prestress and of the prestress optimization. In particular it is shown how, for a generic spatial truss, a suitable cable pretensioning makes us able to assign a geometrical stiffness to the whole structure and, in this way, to improve its overall behavior.

Exploring the potential of climate adaptive building shells

Building shells with adaptive, intuitively offer opportunities for both energy savings and comfort enhancements. Development in this field is still fragmented and the most effective type of climate adaptive building shell (CABS) behaviour is still unknown. This paper explores the potential of CABS by using building performance simulation in combination with multi-objective optimization.

Integrating automatic zone modeling with GA for structural optimization of a composite wing

This work by Embraer and ITA is intended to present a two-step methodology for the structural optimization of a preliminary composite wing based on automatic zone modelling strategy followed by GA iterations.
