Hi all,

I'm attempting to generate a simple linear wave in a 2D tank of length 20m and depth 8m. My mean water depth is 4m and my max free surface displacement is 0.5m giving a free surface peak height of 4.5m and trough of 3.5m.

The wave frequency is 0.5 Hz and the wave length is 3m.

I am trying to develop the wave using CEL expressions for both U and V velocities. These expressions compare well with my basic hand calcs i.e the U velocity decays exponentially as the depth increases.

I am new to this type of work and am a little unsure about a few things:

1. Do I need to specify the inlet surface displacement in the y direction (obtained from the circular particle orbits described in deep water wave theory) aswell as these velocity components?

2. I do not know how to specify the outlet condition, at this stage I am not concerned with reflection, I just want to see a wave propogate through the domain. Surely I cannot specify a pressure as I do not want to constrain this boundary at all, or do I?

Any help would be much appreciated!
