Analysis and Simulations
The case represent a kilo-class submarine totally submerged under a water medium. The interest data for this tutorial is the flow path over the submarine shape and how the water interacts, the pressure points on the structure and the turbulence generated.
Analysis of a pressure regulator valve using the beginning OpenFOAM tutorial from Libre Mechanics Simple beginning 3D OpenFOAM Tutorial.pdf The valve uses the variable change on the fluid path to create restriction to the normal pass , which create a pressure and flow drop on the line, this compact, large-capacity direct-operate pressure regulator are common found on toughest pressure control aplications This kind of equipment can help solve the toughest pressure control applications, Typical applications include superheated steam, steam injection,… Read More »Pressure regulator CFD OpenFOAM analysis.
DOWNLOAD: Simple beginning 3D OpenFOAM Tutorial.pdf OpenFOAM (Open Source Field Operation and Manipulation) it’s an Open Source Software project claim to be one of the best CFD tools currently available, principally be its constant development and its highly technical structure, the fine implementation of common solvers and the possibility to edit and create equations and mathematical cases make OpenFOAM useful tool on researching. OpenFOAM is a C++ toolbox for the development of customized numerical solvers, and pre-/post-processing utilities for the… Read More »Simple beginning 3D OpenFOAM Tutorial
DOWNLOAD: Advanced CalculiX Tutorial.PDF Usual FEA applications involve analysis where multi body assemblies are loaded to determine the contact behavior between each other, some of this data are friction, relative displacement and contact pressure. This kind of cases of study are specially complex and requires much more technological resources due to the nonlinearity characteristics of the case, where a slight change on the geometry, mesh or frontier conditions overcome on a totally different behavior.CalculiX offers a highly custom process to… Read More »Advanced CalculiX Tutorial
Impact its an explicit finite element program wich development and final caracteristics are higly admirable by the way it focus on a simple, yet powerfull structure to solve real world numeric problems under the Time Explicit regimen. The programing language is really simple and can be read and understood from scratch, allowing the user to be more in contact and in control to the analisy’s structure and variables. The program documentation its already on the web and can be get… Read More »First IMPACT Finite Element Program tutorial.
NetGen it’s a powerful 3D tetrahedral mesh generatorl that can handle complex geometries and a great variety of meshing options, the tetrahedral meshs as those created with Netgen are the best option on the selection of a discretization theorem for a non conventional bodycas long as it can handle a decent meshing density , wich it’s possible with the use of current medium-high level processing units. The tetrahedral elements can adjust more easily to the curves and spline surfaces of the model, preserving its proportion form.
The documentation for how to do this is already on the Internet for all of you who knows how to get it, the issue is in all these incomprehensible or wrong sources which can waste our time. Older versions, different programs or libraries, different platforms or just poor documentation is normally found.
Fixing all this here is Tutorial of how to do it easily:
In this video, you will find a useful, “Hello world” step by step example that will help you to understand how this platform works. Importing a 3D model. Meshing. Setting a linear static analysis. Configuring the results. Download the video
The bone is not an uniform material like others usually known on finite element analysis like metals and plastics, this one its compose by layers of distincs materials and diferent propierties. Before anything it is recommended to read first a little about this kind of materials in order to undertand they mechanical conduct. The diference between this material and others is in his espacial – mechanical propierthis, for example, in a regular isotropic material the mechanical propierties are define by… Read More »Humerus analysis, anisotropic material on CalculiX
The already known 2011 version of CAELinux count with some of the best and latest applications meant to be use for analysis and simulations, some of the new features are: Dedicated to CAE , scientific computing and mathematical modelling with emphasis on finite element simulation and computational fluid dynamics Includes the integrated 3D pre-/ post / FE solver package SALOME_MECA 2011.2 (GPL, developped by EDF, France) which represents the fusion of Salome v5.1.3 GUI and Code-Aster STA11.0 finite element solver (updated,… Read More »CAELinux CD Label
Libre Mechanics it’s an Open Knowledge project created to offer a useful platform of information related with the development and research of Mechanical Engineering themes and similar fields, higly related with the use of Open Source and Software Libre tools. Here you will find a wide variety of projects, publications and scientific material available as references for developing their own projects, also guides and tutorials that allow you to take advantage of free software tools available today.
