Excuse me if this question has already been answered, however I searched a lot and didn't find something on the forum.
My question is about the Q field that is created by the OpenFoam Q utility and whether this field is the standard or the normalized Q criterion.
Furthermore, in case that it is not the normalized one, what should it be divided by, in order to achieve normalization?
Thanks a lot in advance,

Q criterion = 0.5*(sqr(tr(gradU)) - tr(((gradU)&(gradU))))
