Hai everyone, beginner of ansys user here. Recently trying to do hydrodynamic analysis the ship interaction, and first i need to run it on hydrodynamic diffraction.
Now, I was testing it by using boxes and the result of solution showed for the two box that i draw(representing ship interaction) is that the water analysis is separated for both box. The expected result is that the both boxes should on the same water surface and not separated. Do anyone know which option i should edit? Or sharing of tutorial link regarding this type of analysis(ship interaction)?
