hello,
I need to make for a simulation a new type of boundary condition. This is my first attempt of programming with openFoam and I'm able to realize a time varying boundary condition starting from oscillatingFixedValueFvPatchField file.
As in oscillatingBC the field varies with time and it is great for a single component field, such as the pressure p. But if I want to vary only a single component of a velocity field for example, I didn't understand how I can do that. I Understood that the field class belongs from List class, and so I tried with a for cycle and edit one by one all the elements of the list (field), but if I try to reach the x() y() or z() method of the single element I get an error because only the vector class have these method..
so how I can reach this method and vary single component of element of the field list?

best regards and sorry for my bad english
