Boat hull Domain for multiphase(Air/water) to study Drag forces

Nomikhan · May 23, 2015, 08:58

Hi all, i am new to gambit, i want to study drag forces on a boat hull with increase in boat speed, since i am new to gambit, i need some guidance regarding meshing the flow domain, because i have two phases (air/water), If someone can guide me how can i separate air and water from each other and how to apply boundry conditions after splitting the domain at the water line ?
Thanks in advance. picture Attached. what should i do next ?

do you already have your geometry ready to mesh?
I don't see your picture

i don't really know how to post that picture here. But its a simle boat and i want to find aerodynamic and hydrodynamic drag on it, i meshed the boat according to the gambit tutorial of Baot geometry, i have tried many different boundary conditions but they did'nt worked,
If you have give me your email so i can forward details
Thank you
