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.

Controlling multiple speed-independent stepper motors simultaneously with Arduino.

Many robotic projects require the control of multiples digital and discrete outputs to work simultaneously, the motor interfaces are not an exception due big robotic instrumentation used today, the widespread Arduino control interface has the ability to handle steppers motors even with its own reference function librarys, but when it comes to a much more basic type of control over multiple speed’s motors some arrangements need to be done.The basic operation of a stepper motor and its advantages like position… Read More »Controlling multiple speed-independent stepper motors simultaneously with Arduino.

Advanced CalculiX 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


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. The program documentation its already on the web and can be get… Read More »First IMPACT Finite Element Program tutorial.

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:
