By Sebastian Rodriguez — [Libre Mechanics] [1]. CalculiX is a package designed to solve field problems.

Also, a cut through the model can be done which creates a section and it is possible to zoom through the model. Since CalculiX uses the standard shape functions for linear elements too, the results must be considered with care.

For a quick overview of the capabilities of CalculiX the results of an investigation of a small jet engine are presented. 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. 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.

As the tuhorial 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.

So if you notice large gaps in the numbering, get rid of cxlculix and you will need less memory. In CalculiX, slave middle nodes in contact formulations are internally connected to their neighboring vertex nodes by means of multiple point constraints.

In addition the eigenfrequencies were calculated to determine possible resonances with the vanes. Furthermore, you get the 3D stress distribution.

In addition the eigenfrequencies were calculated to determine possible resonances with the vanes. If the former is incorrect, so will the latter be. For a quick overview of the capabilities of CalculiX the results of an investigation of a small jet engine are presented. 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.

The CalculiX package was developed by a team of enthusiasts in their raw spare time. The jet engine was build around a turbo-charger rotor in the early 90’s by Andreas Funke and Klaus Wittig. Permissions beyond the scope of this license may be available calculox http: Applying the finite element method to real-life problems is not always a piece of cake. Only a subset of commands which are most important for post-processing is also available through a pop-up menu.

The models are meshed with 20 noded brick elements with reduced integration. The calculations were done to determine the burst-speed and the highest allowable rotational speed concerning low cycle fatigue and creep. The memory needed to run a problem depends on the largest node and element numbers the computational time, though, does not.

This tutorial is intended as a reference or starting point for those who choose calculjx use more high-performance software and control. That way you get the expanded form of these elements in the.

Advanced CalculiX Tutorial

CalculiX is a package designed to solve field problems. This page was last modified on 30 Januaryat The method used is the finite element method. For linear elements this is not the case: This leads to a larger variation in the results if you use linear elements. This program uses the openGL library for visualization and the glut library for window management and event handling. Both programs can be used independently. You can easily verify whether the thicknesses you specified are correct.

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.

Check the calchlix of your mesh in CalculiX GraphiX or by using any other good preprocessor. 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.

Caluclix this precise tutorial it will be assumed that the user its already familiar with the working environment of CalculiX CCX and CGX modules, if this is not the case it is recommendable to refer first to some beginner tutorial for example: Most of the tutorixl recurses as images and this tutorial its available at the sourceforge page.

Static, dynamic and thermal solutions are available.
