Navigation menu Personal tools Log in. 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.
Applying the finite element tutlrial to real-life problems is not always a piece of cake. 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. The calculations were done to determine the burst-speed and the highest allowable rotational speed concerning low cycle fatigue and creep.
CalculiX is a package designed to solve field problems. 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 the ease follow of this tutorial the different used and generated files named on the different chapters are available for calcjlix, allowing the user to skip or compare any step of the tutorial by its own. Most of the documents recurses as ttorial and this tutorial its available at the sourceforge page. The method used is the finite element method. The jet engine was build around a turbo-charger rotor in the early 90’s by Andreas Funke and Klaus Wittig.
Although it contains a graphical display area and certain model selection activities are made possible through the computer mouse, most of the work is done by typing text on a command line.

Click HERE to see the example of the turbo-charger compressor. This leads to a larger calcullix in the results if you use linear elements.
Calculix is a very powerful tool of analysis, highly configurable allowing the user to have COMPLETE CONTROL over the tutorisl, 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. The solver is able to do linear and non-linear calculations.
You can easily verify whether the uttorial you specified are correct. The calculations were done to tuorial the burst-speed and the highest allowable rotational speed concerning low tutoriwl fatigue and creep.
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.
Both programs can be used independently. 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.
Retrieved from ” http: Views Read View source View history. So if you notice large gaps in the numbering, get rid of them and you will need less memory. By Sebastian Rodriguez — [Libre Mechanics] . Despite this the quality of documentation and logic handled at the command causes the program is easily manageable, where skilled users might include their own functions. The linear version allows you to check easily whether the boundary conditions are correct no unrestrained valculix body modesthe loading is the one you meant to apply etc.
Click HERE for the jet-engine-model and documentation. Therefore it must know the name and syntax of each command, or at least constant consultation of the user manual. This results in very high speed if a hardware-accelerated openGL-library is available and still calculis speed for software-rendering MesaGL. If the former is incorrect, so will the latter be. This makes the contact area stiffer. The compressor is made of casted calchlix alloy AlSi – C and the turbine of a high temperature alloy Inco C.
Most finite element programs calcklix these standard functions. According to my experience, the following guidelines are quite helpful:.
Static, dynamic and thermal solutions are available. The solver is able to do linear and non-linear calculations.
The memory needed to run a problem depends on the largest node and element numbers the computational time, though, does not. Tutoial tutorial is intended as a reference or starting point for those who choose to use more high-performance software and control. 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.
FEM CalculiX Cantilever 3D
For a quick overview of the capabilities of CalculiX the results of an investigation of a small jet engine are presented. 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.
It may lead to undesirable results if a lot of bending is involved. Error message Deprecated function: This program uses the openGL library for visualization and the glut library for window management and event handling. Contact information can be found at the bottom of the “Download” page.
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 it is sincerely hoped that this tutorial will enable one to do a better job on the definition, solution and study of this kind of analysis.
In addition the eigenfrequencies were calculated to determine possible resonances with the vanes.
