Deformation of mode shape of solid mechanics eigenfrequency calculation

Hi, I want to calculate the mode shape of the acoustic mode of the waveguide with certain geometry using solid mechanics module. After the calculation, a deformation node was automatically generated with mode shape making the mode profile look a little bit strange. I found the explanation of this deformation node and I just want to make sure that you can only get the actually mode distribution if you set the scale factor to be 1.
Thank you.

As the amplitude of an eigenmode is arbitrary, you can set the deformation scale to anything that provides a nice visualization. The actual scaling of the eigenmode is controlled in the Output section in the settings for the Eigenvalue Solver node.
