Should I use ANSYS AQWA for Hydrostatic stiffness ?

Hello researchers, I am trying to verify a box problem (90x90x55m) which is solved in ANSYS AQWA line manual but using workbench platform. Though my values on the principal diagonal of stiffness...

Is it correct to have a negative sign on principal diagonal in the ANSYS Aqwa hydrostatic stiffness matrix?

I have seen that when center of gravity of the model remains ABOVE center of buoyancy, a negative sign is seen in K44 and K55 terms (ref 3.1.3 AQWA Line User Manual pg 14 of 136). Is it correct...

Is anyone familiar with hydrodynamic analysis of floating offshore wind turbine using TLP?

I am new to ANSYS AQWA. I found out that the undamped natural periods (without the mooring cables) is shown in .LIS file. The structure is actually a TLP floater for wind turbine (ref. attached...
