LincoSim: a Web Based HPC-Cloud Platform for Automatic Virtual Towing Tank Analysis

Abstract

Thanks to evolving web technologies, computational platforms, automation tools and opensource software business model, today, it is possible to develop powerful automatic and virtualized web services for complex physical problems in engineering and design. In particular, in this work, we are presenting a new web based HPC-cloud platform for automatic virtual towing tank analysis. It is well known that the design project of a new hull requires a continuous integration of shape hypothesis and hydrodynamics verifications using analytical tools, 3D computational methods, experimental facilities and sea keeping trial tests. The complexity and the cost of such design tools increase considerably moving from analytical tools to sea keeping trials. In order to perform a meaningful trade-off between costs and high quality data acquiring, during the last decade the usage of 3D computational models has grown pushed also by well-known technological factors. Nevertheless, in the past, there were several limiting factors on the wide diffusion of 3D computational models to perform

Planing Hull Hydrodynamic Performance Prediction Using LincoSim Virtual Towing Tank

“…The standardization of the calm water CFD modeling is based on the physics of the problem that defines the computational domain and the mesh cell sizes according to a given standard mesh topology. See [6,7] for more CFD settings and modeling details. In Figure 2, the domain sizes and the mesh topology are shown for the P43 power boat geometry, which is considered in the present work.…”

“…In [6] an automatic and web-based application of a virtual towing tank named Lin-coSim specifically designed to perform automatic CFD modeling of hydrodynamic performances in calm water was presented. The tool uses only open-source software and deploys high-performance computing infrastructures to take advantage of well-established technological bricks.…”

Research on the design and implementation of computer experiment cloud platform under the application of big data technology

“…Salvadore, F. argues that the rapid development of web technologies, computing platforms, and automation tools provide realistic conditions for developing powerful automated and virtualized web services for complex physical problems in engineering and design. He proposes a web-based cloud platform that allows for automated virtual work [14]. Ait, W. A. argues that cloud-based software combines multiple Web services to satisfy SaaS requests.…”

Web application with data centric approach to ship powering prediction using deep learning

“…Conventionally, 3 the ship design development is performed sequentially in iterations. It 4 involves detailed and laborious calculations, causing long development 5 lead time. 6 In practice, naval architects rely on the parametric design approach 7 as the starting point to estimate the design parameters, evaluating them 8 one at a time.…”
