  • Patch Set : Shows the selected Patch Set

  • View Type : Selects the view type. The default is “X-Y-Z”.

  • Logarithmic Scale : Changes the x-axis to a log scale.

  • dB Plot : Changes the magnitude to a decibel. \(20.0*log10(m_{magnitude} / r_{ref})\).

    • a decibel reference value (= \(r_{ref}\) ) : Default value is 1.0.

    • Draw button : draws the plots using the decibel reference value.

  • Node : The user can see the average or each nodal FFT data.

    • Average : Shows the average data of all nodes on the patch set

    • Single : Shows a Nodal FFT data

  • Draw button : Selects a node including the Patch Set.

  • Frequency : Selects the target frequency for the Vibration Shape animation.

    • Slider Bar and Index is available for the selecting.
