I want to simulate the drift trajectory of a person falling off a ship in a short period of time, considering factors such as wind speed, flow speed, and the ship wave.

However, I have never worked with CFD simulations before.

Recently, I started learning OpenFOAM, and after learning, I chose to use the DTCHullMoving example for practice.

I successfully ran this example, but when I tried to replace the ship with a human-sized rectangular box, there were no errors in the calculation, but the results were poor.

I would like to ask if there are any suggestions, such as what I should consider and what I should pay attention to when modifying the files.

Or could you directly tell me whether it is possible or not for a beginner to use OpenFOAM to achieve my goal?
