how to simulate wave?

hi,everybody! I want to simulate sinusoidal wave varying with time. I don't know how to do, please help me!

What code are you running and where do you want to simulate the wave? I assume you are referring to a sinusoidally varying boundary condition.

Please be more specific.

hello! Robin I use the CFX4.3 software and simulate the free surface between the oil and the water. Now, I want to impose an initial sinusoidal wave disturbance on the water-oil interface at time t=0. I want to study the behavior of the oil-water interface with the wave. I set many kinds of boundary condition, but only see the velocity at the inlet varying with the time and don't see the interface wave. why? I need your help! Thanks!

Use the User-Subroutine USRINT and pose there your initial sinusoidal wave as a variation of the volumefraction VFRAC(INODE,IPHASE)=f(x,y,Phase) in dependence of the location x,y. It is really easy
