This wiki contains simple tutorial models designed to get you acquainted step by step with the concepts and the syntax of ONELAB models.
The list below gives the main new concepts introduced by each tutorial. Explanations are given as comments directly in the models files, which you can browse directly from the list. Useful tips for using the graphical user interface are also available.
You can download all the tutorials on your computer with the command:
git clone http://gitlab.onelab.info/doc/tutorials.gitAdditional examples highlighting various physical models and numerical techniques are available here.
