How can I adapt the SB Analysis to my hull geometry? (in Maxsurf resistance)

Hi my name is Marc,

I'm working on an hidrodinamic study of my boat and i can't adapt the Analysis mesh of Maxsurf Resistance to my hull. I can't upload the file so i put a download link (https://drive.google.com/file/d/10NjVFoSuiNjiCJZLQBIP_AL3zuOqjh9U/view?usp=sharing). If someone can help me let me know.

Also the Slender body method doesn't work.

Thank you!

Sincerely,

Marc
