Eigen frequency; displacement problem

Hi All,
I am having a problem with Eigen frequency simulation of my device. Now the values on the displacement legend plot are not realistic at all to me, though am still new . Considering that the height of the device so attached is 40 mm. The legend shows that the maximum displacement is about 2.85 m? I think there is a problem. Or what does Total Displacement of a Surface mean? But the obtained Eigen frequencies are very reasonable (about 25 kHz).
Any clues or suggestions will be highly appreciated. (See the attached)

Hi,
The scaling of eigenmodes can be chosen arbitrarily, so the magnitude does not carry any physical information.
Any multiple of an eigenvector is still an eigenvector. You can read more about eigenmode scaling in the documentation.
