simulation clipping

[arcfx]

I have a wave simulation that I need to to make look bigger than it is by cloning a few more next to it. So I was wanting to clip out the sides of the walls where the water sticks to. Is this possible some how but still using the Vray Geometry mode?

You can try using the Wrap boundary condition along this axis.

and because the wrapping will produce annoying similarity, you can blend two or three simulations with different width
