Hi, thank you for you reply. Yes, I have tried with the frequency domain statistic analysis as well and the results are as shown in the figure.

  1. I am not sure on the parameters I have specified for the irregular waves. Because although I need the RAOs at precisely 0.71825rad/sec, I am not able to extract the RAOs at this frequency value but instead the closest I get is 0.71975rad/sec. Can you please let me know what the values of the input parameters should be to define the irregular wave as per my requirement?
  2. Also I am not sure why the trend is different for part 10, 13,14,15. Is there anything I am missing? But the article I am trying to validate has used AQWA and have got a very close match with the experimental value. I am not able to figure out what I am missing in the simulation. It would be really helpful, if you can help me out with this.
