Dear All,
I am trying to define the dispersion curves of a periodic unit cell in COMSOL Multiphysics with prescribed displacements. I am using two separate studies:
- Study 1: Stationary, with prescribed displacements on the four edges of the unit cell.
- Study 2: Eigenfrequency.
I intend to use the results of Study 1 as initial conditions for Study 2.
I also conducted a different eigenfrequency study of the same unit cell, and the dispersion curves from Study 2 and this separate study are similar. This suggests that the results from Study 1 may not have been used as initial conditions for Study 2.
Could I be missing any setup errors?
Thank you in advance
Dear All,
The issue has been addressed by implementing a Prestressed Eigenfrequency study. Please remember to include geometric nonlinearity in the eigenfrequency step.
If anyone encounters this problem, feel free to inbox me.
Best wishes,
