Problems about tutorial files
 

Deal All
I am a greenhand of OpenFOAM, so I want to learn how to operate it from the tutorial files. But the user guide does not povide any detail information about the tutorial cases expect the cavity and interFoam cases. I am confouse about other examples and want to know what the other examples talk about.
So is there any documents for describing the detail information about other examples?
Many thanks!

I think you should download and print entire user guide...that was my first taught also...that the documentation is not so great, but if you read entire manual you'll see how things will be clearer over time and constant work with OF.
Here is link where you can download entire User Guide:

All best!

Thank you very much, I will follow your instruction.

The problem is that most of the more advanced tutorials are completely undocumented. There is no explicit info about that setup is being simulated and why, how are the models selected, where is the data (e.g., termochemistry data) taken from, what do most of the nontrivial input parameters mean. From my experience, the most useful resources are the PhD theses http://www.foamcfd.org/resources/theses.html and Chalmers university courses http://openfoamwiki.net/index.php/Handy_links (item 4 as of time of writing). Even though they do not mention specific tutorials (sometimes they do), some relations between descriptions in the theses and tutorial implementations can be traced.
