The method used is the finite element method. Views Read View source View history. 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: In addition the eigenfrequencies were calculated to determine possible resonances with the vanes.

The calculations were done to determine the burst-speed and the highest allowable rotational speed concerning low cycle fatigue calculjx creep. This makes the contact area stiffer. As the user is probably aware by now, the document make a number of simplifying assumptions as the tutorial progressed, this is done in the interest of gaining a clearer understanding of these fundamental without getting bogged down in special details and exceptions.

You can easily verify whether the thicknesses you specified are correct. The solver is able to do linear and non-linear calculations. Calcupix models are meshed with 20 noded brick elements with reduced integration.

Also, a cut through the model can be done which creates a section and it is possible to zoom through the model. Only a subset of commands which are most important for post-processing is also available through a pop-up menu. For example someone may need his own functions to manipulate the result-data or he may need an interface to read or write his own results format. The compressor is made of casted aluminum alloy AlSi – C and the turbine of a high temperature alloy Inco C.

Contact information can be found at the bottom of the “Download” page. The calculations were done to determine the burst-speed and the highest allowable rotational speed concerning low tutroial fatigue and creep. According to my experience, the following guidelines are quite helpful:. This program uses the openGL library for visualization and the glut library for window management and event handling. The right and left side of the disks are connected by cyclic symmetry equations which allow to calculate eigenvalues and mode-shapes for certain nodal diameters of a rotational symmetric volume based only on a segment of the structure.

The compressor is made of casted aluminum alloy AlSi – C and the turbine of a high temperature alloy Inco C and both are loaded by pure centrifugal force. A vda CAD interface is available. If the former is incorrect, so will the latter be.

The method used is the finite element method. That way you get the expanded form of these elements in the. 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 leads to a larger variation in the results if you use tutoral elements. Click HERE to see the example of the turbo-charger turbine. It may lead to undesirable results if a lot of bending is involved. Click HERE for the jet-engine-model and documentation. Most of the documents recurses as images and this tutorial its available at the sourceforge page.

So if you notice large gaps in the numbering, get rid of them and you will need less memory.

Therefore it must know the name and syntax of each command, or at least constant consultation of the user manual. Then presented as an alternative to the 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. If the linear version doesn’t run, the nonlinear problem won’t run either.

The iterative scaling method cf. Based on a work at www. Static, dynamic and thermal solutions are available.

This page was last modified on 30 Januaryat Because the solver makes use of the abaqus input format it is possible to use commercial pre-processors as well. Applying the finite element method to real-life problems is not always a piece of cake.

CALCULIX: A Three-Dimensional Structural Finite Elemente Program

For a quick overview of the capabilities of CalculiX the results of an investigation of a small jet engine are presented. Despite this the quality of documentation and logic handled at the command causes tutogial program is easily manageable, where skilled users might include their own functions.

A simple step reader is included. The solver is able to do linear and non-linear calculations. In addition the eigenfrequencies were calculated to determine possible resonances with the vanes. For a quick overview of the capabilities of CalculiX the results of an investigation of a small jet engine are presented. This is due to the characteristics associated with engineering free-software currently available. This results in very high speed if a hardware-accelerated openGL-library is available and still high speed for software-rendering MesaGL.

The CalculiX package was developed by a team of enthusiasts in their raw spare time. Both programs can be used independently. In CalculiX, slave middle nodes in contact formulations are internally connected to their neighboring vertex nodes by means of multiple point constraints. 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 is a very powerful tool of analysis, highly configurable allowing the user to have COMPLETE CONTROL over the analysis, with more than 18 types of analysis covering most fields of study finite element Calculix’s user can modify any variable on the analysis at discretion, the huge amount of information and documentation on the web make CalculiX a great alternative for the development of research projects where computer tools must accommodate the needs of the study.
