Wrong file in motorBike tutorial?
 
Why the motorBike tutorial (/tutorials/incompressible/simpleFoam/motorBike) has a file called omega inside the 0.org folder which object is actually epsilon?

Here the file content:

Hi,

the standard turbulence model in this tutorial is komegaSST.
Thats why, you need the omega file.
But you can of course switch to kepsilon (then you need an epsilon file).

Thank you val;
what I was saying is that the file is called omega but the object is actually epsilon…

Copy&Paste error most probably. As far as I know that part of the file is always ignored.
