Its main module is designed for the simulation of flows which may be steady or unsteady, laminar or turbulent, incompressible or potentially dilatable, isothermal or not. Scalars and turbulent fluctuations of scalars can be taken into account. The code includes specific modules, referred to as \specific physics", for the treatment of Lagrangian particle tracking, semi-transparent radiative transfer, gas combustion, pulverised coal combustion, electricity effects (Joule effect and elec- tric arcs) and compressible flows. Code Saturne relies on a finite volume discretisation and allows the use of various mesh types which may be hybrid (containing several kinds of elements) and may have structural non-conformities (hanging nodes). The present document is a practical user's guide for Code Saturne version 5.0.0. It is the result of the joint effort of all the members in the development team. It presents all the necessary elements to run a calculation with Code Saturne version 5.0.0. -

Development of a Coupling Approach for Multi-Physics Analyses of Fusion Reactors
Development of a coupling approach for multi-physics analyses of fusion reactors Zur Erlangung des akademischen Grades eines Doktors der Ingenieurwissenschaften (Dr.-Ing.) bei der Fakultat¨ fur¨ Maschinenbau des Karlsruher Instituts fur¨ Technologie (KIT) genehmigte DISSERTATION von Yuefeng Qiu Datum der mundlichen¨ Prufung:¨ 12. 05. 2016 Referent: Prof. Dr. Stieglitz Korreferent: Prof. Dr. Moslang¨ This document is licensed under the Creative Commons Attribution – Share Alike 3.0 DE License (CC BY-SA 3.0 DE): http://creativecommons.org/licenses/by-sa/3.0/de/ Abstract Fusion reactors are complex systems which are built of many complex components and sub-systems with irregular geometries. Their design involves many interdependent multi- physics problems which require coupled neutronic, thermal hydraulic (TH) and structural mechanical (SM) analyses. In this work, an integrated system has been developed to achieve coupled multi-physics analyses of complex fusion reactor systems. An advanced Monte Carlo (MC) modeling approach has been first developed for converting complex models to MC models with hybrid constructive solid and unstructured mesh geometries. A Tessellation-Tetrahedralization approach has been proposed for generating accurate and efficient unstructured meshes for describing MC models. For coupled multi-physics analyses, a high-fidelity coupling approach has been developed for the physical conservative data mapping from MC meshes to TH and SM meshes. Interfaces have been implemented for the MC codes MCNP5/6, TRIPOLI-4 and Geant4, the CFD codes CFX and Fluent, and the FE analysis platform ANSYS Workbench. Furthermore, these approaches have been implemented and integrated into the SALOME simulation platform. Therefore, a coupling system has been developed, which covers the entire analysis cycle of CAD design, neutronic, TH and SM analyses. -

(OSCAE.Initiative) at Universiti Teknologi Malaysia
Open Source Computer Aided Engineering Inititive (OSCAE.Initiative) at Universiti Teknologi Malaysia Abu Hasan Abdullah Faculty of Mechanical Engineering Universiti Teknologi Malaysia March 1, 2017 Abstract Open Source Computer Aided Engineering Initiative (OSCAE.Initiative) is a public statement of principles relating to open source software for Computer Aided Engineering. It aims to pro- mote the use of open source software in engineering discipline with a goal that within the next five years, open source software will become very common tools for conducting CAE analyses. Towards this end, a small OSCAE.Initiative lab to be used for familiarizing and developmental testing of related software packages has been setup at the Marine Technology Centre, Universiti Teknology Malaysia. This paper describes the infrastructure setup, computing hardware components, multiplat- form operating environments and various categories of software packages offered at this lab which has already been identified as a blueprint for another two labs sharing a kindred spirit. 1 Overview The OSCAE.Initiative lab at Universiti Teknologi Malaysia, is located on the second floor of the Marine Technology Centre (MTC). It was established to promote the use of open source software in engineering discipline with a goal that open source software will become the tools of choice for conducting CAE analyses and simulations. Currently, the lab provides • general purpose computing facilities for educational and academic use, and • specialized (CAE) lab environments, software, and support for students, researchers and staff of MTC. Access is by terminals throughout the lab. While users are not required to have their own computers, it is recognized that many do, and facilities are provided to transfer data to and from the OSCAE.Initiative systems so that personal computers and workstations at OSCAE.Initiative lab can complement each other. -
Review of Fluid Structure Interaction Methods Application to Floating Wave Energy Converter
International Journal of Fluid Machinery and Systems DOI: http://dx.doi.org/10.5293/IJFMS.2018.11.1.063 Vol. 11, No. 1, January-March 2018 ISSN (Online): 1882-9554 Original Paper Review of Fluid Structure Interaction Methods Application to Floating Wave Energy Converter Mohammed Asid Zullah1, Young-Ho Lee2 1Geoscience, Energy and Maritime Division, Pacific Community, Private Mail Bag, Suva, Fiji, [email protected] 2Division of Mechanical Engineering, College of Engineering, Korea Maritime and Ocean University, 727 Taejong-ro, Yeongdo-Gu, Busan 49112, South Korea, [email protected] Abstract Computational fluid dynamics (CFD) is a highly efficient paradigm that is used extensively in marine renewable energy research studies and commercial applications. The CFD paradigm is ideal for simulating the complex dynamics of Fluid-Structure Interactions (FSI) and can capture all kinds of nonlinear fluid motions. While nonlinear simulations are considered more expensive and resource intensive compared to the frequency domain approaches, they are much more accurate and ideal for commercial applications. This review study presents a comprehensive overview of the computation fluid dynamics paradigm in context of wave energy converter (WEC) and highlights different CFD tools that are available today for commercial and research applications. State-of-the-art CFD codes such as ANSYS CFX that are highly ideal for WEC simulation problems are highlighted and aspects such as time and frequency domains are also thoroughly discussed along with efficacy of the nonlinear simulations compared to the linear models. The paper presents a comparative evaluation of different WEC modelling codes available today and illustrates the code framework of different CFD simulation software suites. -

Magnus Winter Department of Applied Mechanics Division of Fluid Dynamics Chalmers University of Technology Abstract The use of CFD is widely spread in industry today. However, smaller business have difficulty to make use of this tool, due to high costs for commercial licenses and hard- ware. As SimScale provides the combination of cloud computing with open source CFD software, the prerequisites to use CFD are lowered. -
“Capillary Race” in Circular Tubes Using Openfoam 1 Tutorial
\Capillary Race" in Circular Tubes using OpenFOAM Duc Nguyen [email protected] March 22, 2014 1 Tutorial Overview This tutorial presents two major topics: the introduction to OpenFOAM, a well-known open- source CFD code, and the instruction for using it to obtain numerical results and visual simulation to fluid mechanics problems. In the first part, an introduction to OpenFOAM is presented and followed by the instruction to build OpenFOAM framework on a personal computer. Next, the standard steps to achieve simulation are presented from pre-processing, setting up and controlling the solver to post-processing. These tasks are done by a set of open-source tools and utilities such as Salome, Paraview, PyFoam, etc. which are also covered in this tutorial as part of the OpenFOAM Framework. The fluid mechanics problems for simulation in this tutorial is the phenomenon of liquid column rising in square tubes with different side length in micro gravity environment. This problem is inferred in this tutorial as \Capillary Race" problem. Following the tutorials, the numerical results and visual simulation are obtained to compare with the experimental data using drop tower mentioned in [16]. 2 Introduction to OpenFOAM Framework OpenFOAM [8] is an open-source CFD toolbox started in 2004. The code was initially developed late 1980s at Imperial College and now is distributed by OpenFOAM foundation and maintained by ESI group, a French-based CAE software company. OpenFOAM is a set of solvers and utilities primarily for CFD with capabilities of standard tasks of CFD working flow from pre-processing, solving and post-processing.
