Resistance calculation using Maxsurf

Hi,
I was trying to calculate the resistance on a barge using Maxsurf. I opted to use the KR Barge method for calculating resistance. In theory, the wind velocity is going to affect the resistance. But, changing the wind velocities do not seem to affect the barge resistance, while using KR Barge method. Although, wind shows considerable influence in other methods.
Does the maxurf KR Barge method consider wind forces while calculating resistance?

Thanks

 

Are you using Hullspeed module ? check your settings do define the LWL, and profiles, as it will be a part of Air resistance.
