The rigid body concept is used to fix the two bodies in space. CalculiX FE-Model of a jet engine with turbo-charger compressor blue and turbine red. Like my FreeCAD work? Last edited by makkemal on Wed Feb 08, 1: Static, dynamic and thermal solutions are available. Click HERE for the jet-engine-model and documentation. In addition the eigenfrequencies were calculated to determine possible resonances with the vanes.

The models are meshed with 20 noded brick elements with reduced integration. Did not know that this is possible in CalculiX. Read more about what I do at my blog.

Contact information can be found at the bottom of the “Download” page. Put all files into one directory.

Click HERE to see the example of the turbo-charger compressor. One degree of freedom is left, so they can rotate about their fix-point.


Click HERE to see the example of the turbo-charger turbine. The CalculiX package was developed by a team of enthusiasts in their raw spare mankal.

You do not have the required permissions to view the files attached to this post. The contact feature did need tuning.

I’m still pretty new to this, can you expand on these instructions a little more? Do you think this could be extended to do kinematics-type stuff, like animate a four-bar linkage and show the ,anual stress concentrations throughout the members? The solver is able to do linear and non-linear calculations.

The compressor is made of casted aluminum alloy AlSi – C and the turbine of a high temperature alloy Inco C. The input file is given together with two cqlculix, in order to create an animation with cgx.

The calculations were done to determine the burst-speed and the highest allowable rotational speed concerning low cycle fatigue and creep.

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. Anyone for making an importer into the animation workbench? After some trial and error I got a working bouncing pendulum with just two finite elements.

The method manuwl is the finite element method. 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.

Both programs can be used independently. The surface behavior parameter is way off from the recommendation in the Calculix manual. The driving force is gravity.

Open the results with cgx and there type Code: Because the solver makes use of the abaqus input format it is possible to use commercial pre-processors as well. A simple step reader is included.

CALCULIX: A Three-Dimensional Structural Finite Elemente Program

The jet engine was build around a turbo-charger rotor in the early 90’s by Andreas Funke and Klaus Wittig. For a quick overview of the capabilities of CalculiX the results of an investigation of a small jet engine are presented. CalculiX is a package designed manuall solve field problems. I’d appreciate any level of support via PatreonLiberapay calvulix, or PayPal!

So I tried to find out, if it is possible to do some basic physics with it.
