I'm studying the behaviour of a cylindrical tank full of water, I have used elements SHELL63 for the steel structure and elements FLUID80 for the water,at boundary
I have coupled nodes(coincident, but separates ) of the
fluid and the structure only in the direction normal to the tank's surface. I have not used further elements (CONTACT or TARGET) to the interface fluid structure. I have applied an impulsive displacement (triangular)to the base, but I get too small vertical displacements of the fluid free surface,I have also considered gravity (ACEL command),where have I been wrong?

Can you help me? i couldn't find any documents about water tank in Ansys. How do you define the water inside the tank. My mail gaye2005@gmail.com. help me please.i can draw the tank, but i don't know how i can describe the water or anyfluidelse inside the tank.
