Estimating drag force at the level of water

[paul_cousinie]

Hello,

I'm doing a university project in which I want to observe the impact of a change in the shape of the hull of a rowing boat on the physiology of the rower.

To do this, I would like to estimate the drag force of the boat for my two types of hull in an attempt to observe a reduction in drag force.

I'm having difficulty simulating the fact that the boat is at the air/water interface.

Do you know a way of estimating the drag force at the interface between 2 liquids on Autodesk products?

Thank you in advance for your help.

You cannot do two liquids at the same time without a "solid" boundary between them. I've seen folks create a thin "solid" film between two fluids that is fully transmissible, but it may not capture the wave physics you're looking for. If you are running a free surface analysis, then that won't be an option at all.
