Please select Irregular Wave Response with Slow Dirft, which includes the first order and the second order wave exciting forces.

The first/second order forces mean that the perturbation approach is used to calculate these forces under the small/moderate wave condition. If you want to calculate the time domain responses in severe wave condition, please select Analysis Type of Irregular/Regular Wave Response.
