External Incompressible 3D flow CFD Analysis OpenFOAM Tutorial

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.

First IMPACT Finite Element Program 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.

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

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.

How To Install CalculiX 2.6 multi-thread on Ubuntu

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:
