Reply To: ALE method to simulate wake of a ship

[Reno Genest]

Hello Abhemanyu,

Do you need to model the water in the ship crash simulation? Will the wake have significant effects on the crash results? Do you need to go into the details of drag and boundary layer?

It seems like you have to do a literature review. I think both ALE and ICFD could be used in your case to model the water and the FSI between the ship and water. 

You can search on dynalook.com. Here are some papers that you might find interesting:

Also, these ICFD examples might be useful:

Let me know how it goes.
