Wave Load
You can enter up to four (4) wave load data namely Wave 1, Wave 2, Wave 3 and Wave 4.
You can apply a wave load to the whole or parts of the model. To apply the wave load to the required portion of the layout, input "Y(es)" under the Layout Window > Misc > Loads > Wave Load 1/Wave Load 2/Wave Load 3/Wave Load 4. When done, CAEPIPE internally computes wave load for each element and applies it as a lumped load (i.e., concentrated force) equally at the two nodes of each element (i.e., it is not a distributed load along the element).
The dialog for specifying wave load is given below.

Refer to the Section titled “Wave Load” in Technical Reference Manual for details.
