I think I have searched every corner of internet to find a good step by step tutorial on how to set up a ship/boat simulation in a virtual towing tank. I have found tutorials on how to set up a transient multiphase simulation to calculate drag with a static hull. But it stops there. I find it very limiting and incorrect with a static hull and just water flow around it. Heave and pitch grately affect the drag and lift forces. I really want to learn how to set up and test hull designs with flowing water (to simulate movment of and forces on the vessel like drag,lift and required power). The vessel should atleast have 2dof, ( like a moored boat with heave and pitch affected by bouyancy and lifting forces in regards to speed of waterflow) but it would be cool to learn how to test the vessel with more dof's to test stability and related forces with different load conditions as cargo, inventory, machines, internal tanks etc. Id like to test the vessels in different speeds, as slow displacement and fast planing speeds. Id like to test in calm and wavy water from different angles. The internet is full of Ansys tutorials, but it seems like none that fit my needs. I am a hobbyist and do not have a education, but I got a basic understanding of CFD but the suite of Ansys software is to say the least daunting and not at all intuitive if you are not educated on CFD or physics. So many ways to do the same things, but hard to find out when, what, where, how and why to do the different tasks. Most learning material I find on interesting topics are aimed at CFD educated people and thus is very general and academic not in any way showing how to do it step by step in the actual software. I would really love to se someone make a good Youtube series or a good PDF dedicated to ship/boat simultation and post process analyzis with Ansys software. You know, Ansys marine/ship/boat CFD for dummies like me. I have seen some Youtube videoes demonstrating that Ansys can do what I want. But no where to find a 'how to' or tutorial.
Â
Pretty please someone please make my dream come true. Id love to learn more about this topic.
Best regards,
Tor 😇

I understand your interest in finding comprehensive learning materials for ship/boat simulation using Ansys software. While I don't have a specific YouTube series or PDF tutorial to offer, Ansys does provide a variety of resources that could help you get started and advance your knowledge in fluid simulation with Ansys Fluent, which is applicable to marine applications.
Ansys Fluent is a powerful tool for fluid simulation and offers advanced physics modeling capabilities that can be used for marine and ship CFD simulations. It has user-friendly interfaces and task-based workflows that can help you with turbulence modeling, multiphase flows, and more.
To learn how to use Ansys Fluent, Ansys offers free Ansys Innovation Courses that teach the underlying physics in a problem and how Fluent is used to solve it. These courses could provide a solid foundation for understanding the principles behind marine CFD simulations: Fluids Engineering Courses | Ansys Innovation CoursesÂ
Additionally, Ansys has a YouTube channel with How To Videos that include product-specific tutorials and tips that could be beneficial as you learn the software: https://www.youtube.com/@AnsysHowTo/
For more hands-on learning, the Ansys Learning Hub offers self-paced video courses, CAD models, best practice guides, and demo videos. It also provides learning rooms for questions and discussions where you can learn from Ansys experts Ansys Software Training Center Â
While these resources may not be specifically tailored to marine/ship/boat CFD, they can certainly provide a strong foundation and potentially be adapted to your specific area of interest.
