Hi, in order to give sufficient resolution of low-frequency resonant responses, the program requires a 2-hour duration. You can give less than 7200s wave elevation history, however, as you observed, Aqwa will extend the imported wave elevation time history to 7200 seconds by an approach which is elaborated in Aqwa Theory Manual  Section 2.1.2.3.
