Foam::point::Z
 

Hey there Foamers, I have been asking questions about particular lines of code in OpenFOAM and I thank all those that have explained the lines of coding to me. It has been very helpful. Well, I have another question:

direction Vertical;
Vertical=Foam:: point::Z;

The second line of this code is somewhat puzzling to me. I understand the scope operator is required to access variables contained in a namespace.
