Dear All, I am trying to simulate a hyper-elastic material plate to draw its dispersion curve. I used prestressed eigenfrequency module and applied prescribed displacement on four boundaries of the plate so that it remains pre-stressed. For dispersion curve I need to apply Floquet Bloch boundary condition on four boundaries of my plate. Now at a time on each boundary Periodicity and displacement is applied. When I run the simulation it does not work. I tried stationary simulation separately and simulate the plate with prescribed boundary condition. It works till this stage. Now When I export the result of this simulation to used it in eigenfrequency module using interpolation (int1) function, it gives wrong result. So I wanted to ask, How can I apply the pre-stress condition on plate so that periodic condition should also work and i can get dispersion curve?
Thank you
