This is an old infuriating question climbing up to lawyer offices, which Ansys refuses discussing officially, limiting itself to some cloudy general statements, often telling about fluid dynamics and other products when asked about HFSS.
Since it was discussed, try searching: /forum/discussion/comment/114807
And read ANSYS requirements carefully: automatic mode turns off GPU use.
