Base Tutorial. Topic. Finite Element Analysis. Level If the solver CalculiX is not installed see FEM Install. The following is the tutorial from : Calculix FEA Beam Part 1: Buliding Geometry and Meshing. This article is the first. Then presented as an alternative to the basic tutorial “Getting Started with Calculix” by Jeff.

The calculations were done to determine the burst-speed and the highest allowable rotational speed concerning low cycle fatigue and creep.
Furthermore, you get a feeling what the solution should look like.
Therefore, most finite element programs modify the standard shape functions for linear elements to alleviate these problems. The solver is able to do linear and non-linear calculations. Static, dynamic and thermal solutions are available. This tutorial is intended as a reference or starting point for those who choose to use more high-performance software and control. The calculations were done to determine the burst-speed and the highest allowable rotational speed concerning low cycle fatigue and creep.
By Sebastian Rodriguez — [Libre Mechanics] . This kind of cases of study are specially complex and requires much thtorial technological resources due to the nonlinearity characteristics of the case, where a slight change on the geometry, mesh or frontier conditions overcome on a tutorizl different behavior. Most finite element programs use these standard functions. The FE-model was build from scratch with CalculiX and the compressor- and turbine models together with solver input files can be found in the distribution.
For linear elements this is not the case: Click HERE to see the example of the turbo-charger compressor.

The models are meshed with 20 noded brick elements with reduced integration. This makes the contact area turorial. However, there is no standard way of doing this, so each vendor has created his own modifications without necessarily publishing them.
Check xalculix quality of your mesh in CalculiX GraphiX or by using any other good ttutorial. The solver is able to do linear and non-linear calculations. Then presented as an alternative to calculixx basic tutorial “Getting Started with Calculix” by Jeff Baylo, the reader new on the subject better start with the basic steps explained in detail in that document.
Both programs can be used independently. This results in very tutoriao speed if a hardware-accelerated openGL-library is available and still high speed for software-rendering MesaGL. Static, dynamic and thermal solutions are available. The FE-model was build from scratch with CalculiX and the compressor- and turbine models together with solver input files can be found in the distribution.
If you include contact in your calculations and you are using quadratic elements, first avoid to include middle nodes in the slave surface. The linear version allows you to check easily whether the boundary conditions are correct no unrestrained rigid body modesthe loading is the one you meant to apply etc.
Therefore it must know the name and syntax of each command, or at least constant consultation of the user manual.
This program uses the openGL library for visualization and the glut library for window management and event handling. Error message Deprecated function: By no means it hast the complete history of contact handling on CalculiX, it is much broader in scope that can be presented in a single document such as this, but tugorial is sincerely hoped that this tutorial will enable one to do a better job on tutoeial definition, solution and study of this kind of analysis.

Despite this the quality of documentation and logic handled at the command causes thtorial program is easily manageable, where skilled users might include their own functions. Click HERE to see the example of the turbo-charger turbine. If the linear version doesn’t run, the nonlinear problem won’t run either.
The method used is the finite element method. For the ease follow of this tutorial the different used and generated files named on the different chapters are available for download, allowing the user to skip or compare any step of the tutorial by its own. The standard shape functions for quadratic elements are very good.

However, adhering to a couple of simple rules can make life a lot easier. CalculiX is a package designed to solve field problems.
Views Read View source View history. As the user is probably aware by now, the ttuorial make a number of simplifying assumptions as the turorial progressed, this is done in the interest of gaining a clearer understanding of these fundamental without getting bogged down in special details and exceptions.
According to my experience, the following guidelines are quite helpful:. Especially achieving convergence for nonlinear applications large deformation, nonlinear material behavior, contact can be quite tricky. That way you get the expanded form of these elements in the. A vda CAD interface is available. Contact information can be found at the bottom of the “Download” page.
