Hello!
I am a new user of OpenFoam. I was looking at the damBreak case and nozzleFlow2D case. Both the cases require setting a non uniform gamma field. However, the damBreak case uses setFields utility to do this while nozzleFlow2D uses cellSet utility. Is there a particular reason why this is done? When I looked at the user manual, I saw that both these utilities are for selecting a cell set through a dictionary- one does it in preprocessing while the other does it in mesh manipulation.
Can somebody please help me know why two different dictionaries are used here?
