The models are meshed with 20 noded brick elements with reduced integration. Click HERE to see the example of the turbo-charger turbine. After some trial and error I got a working bouncing pendulum with just two finite elements.

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. Put all mmanual into one directory.

Did not know that this is possible in CalculiX.

Contact information can be found at the bottom of the “Download” page. The solver is able to do linear and non-linear calculations. So I tried to find out, if it is possible to do some basic physics with it. Last edited by makkemal on Wed Feb 08, 1: For a quick overview of the capabilities of CalculiX the results of an investigation of a small jet engine are presented.


The method used is the finite element method. The surface behavior parameter is way off from the recommendation in the Calculix manual.

I’m still pretty new to this, can you expand on these instructions a little more? 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.

Click HERE for the jet-engine-model and documentation.

The CalculiX package was developed by a team of enthusiasts in their raw spare time. The input file is given together with two scripts, in order to create an animation with cgx. 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? Static, dynamic and thermal solutions are available.

The compressor is made of casted aluminum alloy AlSi – C and the turbine of a high temperature alloy Inco C. The driving force calculid gravity. One degree of freedom is left, so they can rotate about their fix-point. You do not have the required permissions to view the files attached to this post. Do you think this could be extended to do kinematics-type stuff, like animate a four-bar linkage and show the time-dependent stress concentrations throughout the members?


The rigid body concept is used to fix the two bodies in space. Open the results with cgx and there type Code: Click HERE to see the example of the turbo-charger compressor. Both programs can be used independently. The contact feature did need tuning. Like my FreeCAD work? I’d appreciate any level of support via PatreonLiberapayor Mqnual Because the solver makes use of the abaqus input format it is possible to use calculjx pre-processors as well.

In addition the eigenfrequencies were calculated to determine possible resonances with the vanes. The jet engine was build around a turbo-charger rotor in the early 90’s by Andreas Funke and Klaus Wittig. CalculiX FE-Model of a jet engine with turbo-charger compressor blue and turbine red. A simple step reader is included. Read more about what I manul at my blog.
