Hello, i'm student of naval architecture, and i want to learn CFD for ships on ANSYS. Can someone say an playlist on youtube, an ebook, or something like that for i study?

Unfortunately there are not a lot of tutorials available for flow around ships. The closest I could find is the symposium presentation in which they use Ansys Fluent:

Using Computational Fluid Dynamics to Predict Drag on a Boat Hull

A few pages from the presentation:

For CFX, I'd really suggest you to go through the following youtube tutorial:

ANSYS CFX - TUTORIAL Free Surface - CFD Simulation

Hola denis , has logrado estudiar el comportamiento de flujos en buques? tengo que resolver un problema con el movimiento al rededor de un casco de un buque en el movimiento de roll , estudiando la estabilidad del buque , tienes algo sobre eso? saludos

Hi Kevin, what specifically do you want? Because, if I understand you, you need to solve a problem where the ship is sailing through an irregular sea and the waves are colliding against the hull, from this you want to analyze the stability of the boat in the row movement? it is?

If you want to know only about the stability in row motion (up to when the boat can tilt), you can calculate the hydrostatic curves of it, and see if the radius of restitution is in accordance with the norm where it will sail to be considered stable.

Yes, I want to simulate the stability in movement of the row (until angle can be tilted) to later validate the model with the hydro static curves, if you have any reference material to this I would be very grateful, my email is: ksansandoval@gmail.com , Beforehand thank you very much!
