I am using the ANSYS20 to simulate the piezo-energy harvester. However, i can not obtain the voltage output in frequency voltage plot as attached. And, it keeps showing the message " The maximum contact stiffness is too big. This may affect the accuracy of the results. You may need to scale the force unit in the model."
How could i deal with these problems to obtain the voltage.
