Hi,

What exactly do you want to do? Modelling waves can be very tricky because of the nature of the problem. You have moving boundaries, and I would not trust any of the commercials programs that are available.

I am afraid so. You could find programs (like femlab or fluent) that will try to model your problem, but I would not trust them.

I have not yet developed codes to simulate 3D flows, but I did develop code to simulate waves in 2-D.

?? I am quite lost!

You are asking for my help, but you are not telling me what you want to do!

What physical problem are you trying to solve? What are the boundary conditions? What is the geometry of your problem?

Which version of FLOW-3D are you using? Since version 9.2 on (now the last release is 9.3) you can model directly from the gui many kind of waves!
