We calculate four types of initial vorticities in Au[Formula: see text][Formula: see text][Formula: see text]Au collisions at energies [Formula: see text]–200[Formula: see text]GeV using a microscopic transport model PACIAE. Our simulation shows the nonmonotonic dependence of the initial vorticities on the collision energies. The energy turning point is around 10–15[Formula: see text]GeV for different vorticities but not sensitive to impact parameter.
