Dagar This tutorial is intended as a reference or starting point for those who choose to use more high-performance software and control. CalculiX is a package designed to solve field problems. The solver is able to do linear and non-linear calculations.

Most of the documents recurses as images and this tutorial its available at the sourceforge page. Click HERE for the jet-engine-model and documentation. 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. Doc:Calculix In CalculiX, slave middle nodes in contact formulations are internally connected to their neighboring vertex nodes by means of multiple point constraints. The models are meshed with 20 noded brick elements with reduced integration.

The memory needed to run a problem depends on the largest node and element numbers the computational time, though, does not. Static, dynamic and thermal solutions are available. The calculations were done to determine cslculix burst-speed and the highest allowable rotational speed concerning low cycle fatigue and creep. This results in very high speed if a hardware-accelerated openGL-library is available and still high speed for software-rendering MesaGL. The calculations were done to determine the burst-speed and the highest allowable rotational speed concerning low cycle fatigue and creep.

According to my experience, the following guidelines are quite helpful:. This leads to a larger variation in the results if you use linear elements. 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.

This program uses the openGL library for visualization and the calcilix library for window management and event handling. Advanced CalculiX Tutorial Libre Mechanics Shaded animations of static and dynamic results, the common color plots and time history plots capculix be created. The CalculiX package was developed by a team of enthusiasts in their raw spare time. 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.

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 standard shape functions for quadratic elements are very good. This makes the contact area stiffer. The method used is the finite element method. Furthermore, you get the 3D stress distribution.

Please keep in mind that any file may vary from user to user by the meshing and computational conditions, but it does not meaning this difference will represent an error of processing.

Click HERE to see the example of the turbo-charger compressor. Most finite element programs use ttutorial standard functions. Both programs can be used independently.

Therefore it must know the name and syntax of each command, or at least constant consultation of the user manual. 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.

It may lead to undesirable results if a lot of bending is involved. Because the solver makes use of the abaqus input format it is possible to use commercial pre-processors as well. Furthermore, you get a feeling what the solution should look like. Views Read View source View history. Related Posts.
