Increasing passive safety performances using an automatic CAE methodology
In the automotive industry, safety requirements are more and more stringent leading to engineering challenges in finding the best tradeoff between crashworthiness performances, structure weight, design and production costs. The goal of the activity is to develop an automatic optimization work flow for a car door. The final objective is to fulfill the safety requirements and obtain the best rating in the pole test.
Design optimization of a main landing gear shock absorber hydraulic system
The present study describes the advantages obtained by the usage of the modeFRONTIER software for the design optimization of a Main Landing Gear (MLG) shock absorber hydraulic system to guarantee the compliance with the customer performance requirements.
Risk Mitigation for Unmanned Air Vehicles Mission Planning
The present work (developed into the co-funded project “TAKE-OFF - Test and Knowledge-based Environment for Operations, Flight and Facility”, whose frame is the “Cluster Tecnologici Regionali - SmartPuglia 2020, Regione Puglia”) introduces a path planning methodology where the risk related to UAV operation is reduced by estimating the probability of hitting a person on the ground, assuming a map of the population density in the area interested by the flight is available.
Effective toolchain for the model based development of an EUVI exhaust aftertreatment system
BASF, as a leading global catalyst supplier, was approached by a commercial truck manufacturer to improve cost and performance of the current EUVI production exhaust after treatment system.
ESTECO webinar recording | Shroud Design Exploration using PowerFLOW integrated with modeFRONTIER
ESTECO and EXA hosted a joint webinar on December 14th 2017, presenting the successful integration of PowerFLOW simulation technology in the modeFRONTIER workflow to provide Ditch Witch® with valuable insight to guide the shroud design on one of its Vacuum Excavators.
Performance of diﬀerent optimization concepts for reactive ﬂow systems based on combined CFD and response surface methods
Optimization of reactive flow systems, e.g. coal and biomass combustion, gasification or partial oxidation, is usually a multi-parameter problem, while geometry configurations (e.g. reactor dimensions, burner dimensions) and operating conditions (e.g. fuel mass flow, reactor temperature, cooling capability) mainly determine the process efficiency and profitability.
Sensitivity analysis of the dynamic response of an electronic fuel injector regarding fuel properties and operating conditions
Electronic fuel injectors play an indispensable role in High Pressure Common Rail (HPCR) fuel injection systems and interest numerous researchers to improve their performance. This paper investigates the sensitivity of three fuel properties (the fuel density, bulk modulus and absolute viscosity) to the valve opening/closing delay and the valve opening/closing time.
Sensitivity analysis of urban morphology factors regarding solar energy potential of buildings in a Brazilian tropical context
Planning the urban morphology of the built environment is a key issue in shifting to a climate adapted urban environment. This paper addresses an important threefold energy challenge of tropical cities: the major potential of harnessing solar energy as renewable resource for local electricity production and the energy-saving paradox of reducing the undesirable solar heat gains in buildings while providing satisfactory levels of daylight. It aims at measuring the effect size of urban form factors regarding these energy goals.
Situated Design Optimization of Haptic Devices
It is a complex task to develop and optimize a high-performing haptic device, mainly because of the multi-domain and multi-criteria performance requirements for such devices. The general goal for the research presented in this paper is to further develop the previously proposed model-based framework and methodology into a situated and computationally efficient design framework for multiobjective optimization of haptic devices.
White Paper | Aerodynamic Design Best Practices Using PowerFlow and modeFRONTIER optimization
The example in this paper is an aerodynamic guidance study of a generic SUV-type vehicle. The goal was to understand the impact of rear end design changes to provide guidance for achieving minimized drag, while also considering rear lift and side force fluctuations. The project was conducted on ExaCLOUD, which provided secure, web-based access to the complete Exa simulation software suite and modeFRONTIER.
