Dear All,
I am trying to simulate a hyper-elastic material plate in COMSOL Multiphysics 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
You can calculate with two steps in one solve process. First step is stationary simulation for pre-stress. Second step is to sovle eigenfrequency with pre-stress.
Dear Hongping Hu,
The prescribed displacement and periodic conditon does not work at same time. This is main issue
if you could comment.
Thank you
