Drum Winch for Nonlinear Polynomial Cables. You can define a drum winch on a nonlinear polynomial cable using the DW10, DWAL, LNDW or NLDW data records.

Increased Limit for Number of Elements. The 64-bit version of Aqwa can accept up to 60,000 elements, of which 30,000 can be diffracting.

Maneuvering Force/Moment for Aqwa-Drift. You can now use the MNVR run-time option for all time response analysis types to request calculation of low frequency maneuvering loads.

Mean Drift Force Coefficient Correction. The mean wave drift coefficient now includes current interaction and viscous effects in accordance with DNV guidance (DNVGL-OS-E301, Position mooring).

Radiation Force with Hot Start. When running a hot start analysis, the motion response at the time steps prior to the hot start time are used in the convolution integral for the radiation force calculation.

Ship Position/Course Control. You can define horizontal motion PID controllers in an Aqwa solver time domain analysis. This can be used to retain the travelling course or maintain a horizontal position of a structure.

Warped Elements Check. The solver checks that nodes of a diffraction quadrilateral panel are in a flat plane.
