Welcome to the ROHR2 training page.
This page offers ROHR training material referring to specified tasks.

The training material is stored in different file types:

1. Online flash movie: The task solution is presented in an animated movie file. Click on the movie link to start and follow the instructions. The green navigation buttons allow you to go forward or backwards in the tutorial .

2. PDF copy of the movie. If the movie format can not be executed on your computer, please open the pdf which includes the video contents.

3. Zip file containing the calculation data of the example.
For your own exercises the ROHR2 data of the calculation is added in a zip file. Download and copy the data to your ROHR2 project directory, then start the *r2w file to run the example in your ROHR2 license or demo license.

4. Zip-file containing  complete movie and calculation data for download.

For general introduction, please download the ROHR2 tutorial,
available in German or English
