Plot wave patterns on the ship hull using paraview
 

I am studing the DTCHull case in openfoam. I run the simulation. Now I am trying to plot the wave patterns on the hull using paraview.
Somebody please help me how to plot the wave pattern on the ship hull using paraview. I am attaching a photo of what I am trying to get from paraview.
Any help is highly appreciated
Keenly waiting for a reply
