Hi, <\/p>\n

I am trying to validate a single floating structure using ansys AQWA. I am using this article as a reference to which I am trying to validate my simulations – https:\/\/doi.org\/10.3390\/jmse9091028<\/a><\/p>\n

My simulation setup is as follows :- <\/p>\n

<\/p>\n

I am currently validating the results of the hydrodynamic diffraction through RAOs and the results are as follows:<\/p>\n

<\/p>\n

As it can be seen from the plots, there is a clear difference with my simulations and the results from the reference article. I have ensured that the mass and interial properties are correct. I have also performed a mesh independence and a domain independent studies. Based on doing all these, I still get differences in the results and I have some questions regarding this which are as follows:<\/p>\n

    \n
  1. What could be the cause of this difference in results? <\/li>\n
  2. Do I have to include an additional damping matrix?<\/li>\n
  3. How do I determine the damping matrix as the reference article does not mention it?<\/li>\n
  4. Also for the mooring lines, I am not sure where I need to define the pretension of the cables because I dont find the option.<\/li>\n<\/ol>\n

    Please let me know what I am missing out and how to solve this issue.<\/p>\n

    Thanks!<\/p>\n","protected":false},"template":"","class_list":["post-373315","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
