Hello,

do you know a manual of Open Foam which starts from the beginning? I can use Fluent, but I have never used Open Foam. All the tutorials and manuals that I have found, do not describe, for example, how are the numbers between brackets in the mesh generations. These manuals assume already that the reader knows what they are. For example, in a classical tutorial I read "hex (0 1 2 3 4 5 6 7) (20 20 1) simpleGrading (1 1 1)", but I don't know what (20 20 1) refer to, or what simpleGrading (1 1 1) is.
I need a very simple and practical manual for beginners, where all is explained from the beginning.

Thank you

well actually, the openFoam.org user guide as well as the openfoam wiki are great websites for that issue. for example, everything you have asked for is written in the blockMesh user guide.
http://cfd.direct/openfoam/user-guide/blockmesh/

simply read the user guide about the utilities. of course, there are many things left out in the documentation but the basics you need for the beginning, are perfectly captured.
I have also used fluent for years before migrating to OF. You'll get used to it pretty quickly and also learn a lot about cfd in general as OF isn't as much of a black box as fluent.
