# Parametric CalculiX-Examples
Created by Martin Kraska, Brandenburg University of Applied Sciences

These examples demonstrate the use of [CalculiX](http://www.dhondt.de/) 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](Scripts/) for usage hints.

The [Setup](Setup.md) 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](https://addons.mozilla.org/en-US/firefox/addon/toggle-animated-gifs/) to add replay controls.

In the [Release Manager](https://github.com/mkraska/CalculiX-Examples/releases) 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.
