Hi all,

For some time I`m struggling with the values in REFERENCE VALUES tab in Fluent, the area and the length. I read the manual, but informations there are really poor about them.
I`m studying flow over surfboard fin, and I need to study lift & drag coeff`s, but without propely define area and length values, I`m stuck.
My question is: Do those values refer to the area of the surface, where lift is occuring or to the whole suface of an object? If there are, say, 3 fins, what area I should put?

Thanks in advance for any tip and hint.
