I am a high school student and currently I am working on a project in Rhino. I am designing a fishing lure and soon we are planning on 3-d printing it but before that, we want to see how it flows in water. So the big question is what would be the best way to do that? After a little research we found out about the program called Grasshopper and saw a few youtube videos showing that it is possible to do fluid dynamics with this program. Any help would be greatly appreciated!
