      Hi, everyone

      I'm doing the harmonic analysis of langevin transducer, but the deformation results is not what i expected. The amplitude in the front surface of the transducer should be about 5um.

      This is the result.

      Did you specify damping? If the excitation is at resonance, damping is needed to limit the response.

      No, how to set the damping?
