The rigid body concept is used to fix the two bodies in space. Click HERE for the jet-engine-model and documentation. Like my FreeCAD work?

In addition the eigenfrequencies were calculated to determine possible resonances with the vanes. Both programs can be used independently. You do not have the required permissions to view the files attached to this post. Calcilix input file is given together with two scripts, in order to create an animation with cgx.

Static, dynamic and thermal solutions are available. Read more about what I do at my blog. The contact feature did need tuning.

Contact information can be found at the bottom of the “Download” page. CalculiX is a package designed to solve field problems. The compressor is made of mqnual aluminum alloy AlSi – C and the turbine of a high temperature alloy Inco C. 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.


The CalculiX package was developed by a team of enthusiasts in their raw spare time. Click HERE to see the example of the turbo-charger turbine. Did not know that this is possible in CalculiX. Because the solver makes use of the abaqus input format it is possible to use commercial pre-processors as well. The models are meshed with manyal noded brick elements with reduced integration. For a quick overview of the capabilities of CalculiX the calculixx of an investigation of a small jet engine are presented.

One degree of freedom is left, so they can rotate about their fix-point.

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.

Anyone for making an importer into the animation workbench?

Click HERE to see the example of the turbo-charger compressor. The jet engine was build around a turbo-charger rotor in the early 90’s by Andreas Funke and Klaus Wittig.

I’d appreciate any level of support via PatreonLiberapayor PayPal! A simple step reader is included. Do you think this could be extended to do kinematics-type stuff, like animate a four-bar caculix and show the time-dependent stress concentrations throughout the members?


The surface behavior parameter is way off from the recommendation in the Calculix manual. Put all files into one directory.

The method used is the finite element method. After some trial and error I got a working bouncing pendulum with just two mxnual elements.

So I tried to find out, if it is possible to do some basic physics with it. I’m still pretty new to this, can you expand on these instructions a little more? CalculiX FE-Model of a jet engine with turbo-charger compressor blue and turbine red.

The driving force is gravity. Last edited by makkemal on Wed Feb 08, 1: The solver is able to do linear and non-linear calculations. Open the results with cgx and there type Code: The calculations were done to determine the burst-speed and the highest allowable rotational speed concerning low cycle fatigue and creep.
