  • Optimization of a Wing-Sail shape for a small boat

    The described optimization process is a very powerful instrument to investigate the influence of a wide range of geometrical parameters on wing-sail​ behavior. The analysis was conducted with the coupling of STAR-CCM+ and modeFRONTIER with the goal of increasing wingsail performance in a small boat.

  • A CFD-based multidisciplinary optimization of aeroelastic systems with coupled reliability constraints

    Designing aeroelastic systems with maximum reliability is studied in this paper using an AGARD 445.6 aircraft wing. Applications of RBDO techniques with a multidisciplinary code coupling approach based on high-fidelity CAD, CFD and CSD softwares and fluidstructure interface is presented with the aim of constructing a fully automatic design framework for aeroelastic optimization problems.

  • Air Intake Manifold Design 1D-3D fluid-dynamic multi-objective engine performances optimization

    This study aims to optimize an air intake manifold by adding 1D and 3D analysis to the optimization methodology in order to reach optimal geometry and performance. Torque and power performance is analyzed with a 1D Gt-Power model and the fluid-dynamic balance is performed with the CFX 3D fluid-dynamic code. modeFRONTIER was chosen to run the optimization process.

  • Method for estimating parameters of practical ship manoeuvring models based on the combination of RANSE computations and System Identification

    A method for estimating parameters of practical ship maneuvering models based on the combination of RANSE computations and System Identification (SI) procedure is investigated. The test case is a rather slender twin screw and two rudders ship. The genetic algorithm MOGA-II available in modeFRONTIER was used for the optimization procedure

  • Design, Analysis and Multi-Objective Constrained Optimization of Multi-Winglets

    In this project a prototype Boeing 7E7 wing is optimized with various winglet configurations and with slight cost effective modifications to the existing design. With the optimized winglet configurations, greater efficiency such as increased range, a reduction of fuel consumption, and safer and steadier flying conditions will be realized, benefiting both consumer and environment.

  • Petrobras Designs the P-55 platform using modeFRONTIER

    In 2014 Petrobras, a state-owned publicly traded Brazilian multinational energy corporation headquartered in Rio de Janeiro, Brazil, launched their P-55 offshore platform, which was initially sized using modeFRONTIER. In order to tackle the complex problem of multiple variables, constraints and objectives, as well as a desire for a rational approach to the design process, Petrobras turned to modeFRONTIER to help them with the optimization study.

  • Optimization of a Turbo Charger Compressor at BorgWarner using AxCent and modeFRONTIER

    This work presents a numerically optimized design approach to turbo charger radial compressor development for commercial diesel applications. The design optimization includes both aerodynamic and structural components, combined via a “loosely coupled” iterative procedure. The primary goal of the design is to maximize total to static efficiency at various operating conditions, while also preserving or expanding the overall operating range of the compressor, and doing so with a structurally sound geometry.
