Hai guys.
Recently trying to do hull definition on Design Modeler to define the above/below water line for Hydrodynamic Analysis later on.
By referring to some tutorials, some tutorials did the "Thin/Surface" before "Freeze" and "Slice" the structure, while some tutorials not doing it.
May I know is it necessary for doing the "Thin/Surface"? And what is the main purpose or function of the "Thin/Surface"?
Thanks in advance.

The thin surface is to make the body a shell surface to allow for hydrodynamic diffraction and response in ANSYS AQWA. Anyway, I hope it is sorted
