CFD in a boat

      Hello, I would like to conduct the following multiphysics project and I would like to know some details on how do you suggest doing it.

      I want to simulate a boat in water (for such I'll use the multiphase flow), my question is, depending on the weight and the loads and its locations on my boat, it will have a degree according to the flat-water. How can you simulate this equilibrium between boat and water, in order to determine my model and flatwater line location to then conduct the multiphase CFD analysis?

      Regards,

      Manuel

      You can use the 6DOF solver to allow the boat to float/pitch/yaw based on the flow but that'll take more knowledge of the software and a longer run. To start with I'd fix the boat location and look at the wake etc.

      Thanks Rob Do you know of any good resource/tutorial to further understand the 6 DOF solver?
      I would like to start with an easy geometry as the current project I am doing is more of an optimisation nature
      Thanks for the first hint on where to look at

      If you're doing an optimiser study I'd start with a fixed position: the 6DOF runs will be even harder to converge than normal multiphase. If you click on Help there are a load of tutorials and links to the Ansys YouTube channel. There are additional materials on the Ansys Learning Hub but you need a (paid for) subscription for those.
