Hi,
I am a civil engineering student and am trying to model a reclamation project with Plaxis-2D. I was trying to study the lateral deformation caused by wave loading on the artificial island, but since the boundaries are fixed, no lateral deformation is allowed. I tried to use line displacement and set x-displacement as "free" while keeping other boundary conditions as default settings. However, an error was shown when I calculate the result. I knew setting line displacement as "free" means that the model is floating in the air, and thought only setting x-displacement as "free" would be fine. Apparently that was not the case. Therefore, I would like to know, if I wanted to simulate the lateral deformation caused by the wave loading, what should I do to allow the calculation to do done? Thanks!

Hello Lok Hei Lee,
For the static analysis, although the boundaries are fixed, there is still horizontal deformation in within the model. If you run a dynamic analysis, the boundary conditions now need to be used “dynamic” conditions under Model conditions in Model explorer. We have a tutorial for this kind of analysis, you may refer to it.
