Piezo stack error for help

When I simulate a piezo stack for energy harvesting, there is a message:

['OneDOFMSD/Solver Configuration']: At time 0.032100, one or more assertions are triggered.

Stack deflection must be greater than Minus piezo layer thickness times number of layers.

Does anyone encountered this kind of error? Thank you very much if you could help me out.

Hi

It seems like the solver is not able to converge to a solution. You can try the below trouble shooting steps:

1. Make sure that the initial conditions are specified correctly.
2. Ensure that the signal units are same across the model.
3. Ensure that a variable step solver is used

Let me know if this is helpful
