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.
How to mesh complex geometries on NetGen and properly analyse on CalculiX
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.
