Hello to everyone,
How can I calculate the resistance for a trimaran boat form?
I created my model as trimaran in maxsurf modeler correctly, but I can't find a part in the resistance module where I can choose the trimaran.
Images are below:
Thank you for your answer.
Best regards.
Hi Mehmet,
You have two real options here:
1) Use the Slender Body Method, ensuring you define the three demihulls in Analysis | SB Analysis Geometry.
- Read the manual from page 25 onwards.
- You will need to determine a suitable trimaran Form Factor
2) Analyse your main hull and demi-hulls separately and sum the resistance.
- This won't account for the interaction between demihulls.
One of the great things about the Slender Body method is that you can calculate the far field wake pattern (Analysis | Calculate Free Surface) and observe how the hull / demihull wakes interact. You can use this to help locate the hulls differently.
Regards,
James
