Hello @Jason.Jonkman

I am studying the dynamics of ITI Energy Barge and i have two questions.

1- My first question is about AeroDyn 14. When i look to the input file, i do not see an option **compute tower aerodynamic loads** like in AeroDyn 15. I was wondering on how to take into account the aerodynamic loads on the tower ? (i mean the aerodynamic loads along the height of the tower and not the thrust force from the rotor). Below a screen capture of AeroDyn 14 input file.

Could you please help me ?

2- My second question is related to the barge itself. It is stated in ElastoDyn input file (i mean the default file, i did not change anything ) that tower base starts at mean sea level. I have a difficulty to imagine the barge since it is stated otherwise (i think in D. MATHA Ph.D. thesis) that the barge has a draft of 4 m and a freeboard of 6 m which means for me that tower base should start at +6 m knowing that the reference point is taken at the mean sea level. Below a screen capture of ElastoDyn input file (the line highlighted in yellow).

What do you think ?

Thank you in advance.

Best Regards,

Riad
