Hi,

I have some problems in understanding the forces output. I am looking at rudder and keel (both 2d and 3d)of a sailing boat. And everytime I have that pressure forces are by far superior than viscous forces (in all viscous models used) it is something I dont understand possible at 0 of attack. It is maybe a problem in Fluent setup or what i understand of CFD

Thank you
