I have a 3D Sketchup model of a simple boat (it is a solid, if that matters) that I would like to test to see if it floats when given a certain density and load. I will eventually print the model, but first I'd like to simulate it to see if it floats and possible how well it steers. Basically, I want to put the model in a simulated bathtub.
If it has other features such as seing how it behaves under propulsion, that would be a bonus but it is not necessary.
I have access to nearly every AutoDesk product through a student license, but don't know how to use any of them, so I would prefer a simple free program. If there is an AutoDesk program for this, I would like to know, however.
