These examples demonstrate the use of CalculiX for various analysis types. Most of them use parametrized geometry generated in CGX, some use GMSH for geometry and meshing.
Also, there are some helper python scripts. See Scripts page for usage hints.
The Setup page provides instructions on how to setup the working environment under Windows and Linux.
Click the preview images to view the examples.
This page uses animated gifs. In Firefox, you might want to install the plugin Toggle Animated Gifs to add replay controls.
In the Release Manager you can download the examples for your version of CalculiX. Oldest available version is 2.10. Note that only the current version is under maintenance.
