I need to model a boat running on the water in waves. Can anyone help me set up the physics and how to simulate this problem in Simscale?
The second relevant question is if I can use oblique waves for a boat which is running at a certain speed?
Can I get drag and motions accelerations as output? (Maybe Heave, Pitch and Role).
Hi!
As far as waves go, there’s not a ‘dedicated’ module that allows you to create waves - normally what I see is waves being created with an initial condition for phase fraction (e.g. like in this project).
Drag is easy to get with a forces and moments result control. As far as the other outputs go, maybe with the “Ship design analysis” solid body motion definition?
To be honest I’ve never explored this option before, but you might be able to find some public projects.

Hi @LeoNowruzi02,
Ricardo’s input here is very helpful, as always!
We also have this old project that might be helpful:
You can try and observe how the analysis was set up and apply that to your own simulation.
One quick comment is that this is done using the Multiphase analysis type, which is not available to Community users. If you’re a student, the Multiphase solver is available under our Academic Program though.
Cheers
I did apply for student account online. I Sent an email, and I am waiting for the response. But I haven’t received any response yet. I read the thread for this project and the conversation is interesting. But they have not modelled degrees of freedom nor the wave generation. Besides, as well mentioned, I cannot see the settings of the project due to my account status. Furthermore, there’s no example on the forum or tutorials to show a boat in free surface in the wave with some degrees of freedom. Is there any way you can help me achieve this? Also, how much should I pay to buy a licence? Thanks
It seems like everything is settled now - great!
Could you exapnd on the degrees of freedom point? I’m not sure what you’re going for here - do you want to be able to model wave generation in multiple directions? Was Ricardo’s advice on how to generate the waves not helpful?
To request a quote, take a look here. However, please note that the professional license is usually provided for commercial applications!
Cheers
