The output of a modal FE body is introduced in FE Body Output. To show the stress and strain, the recovery process is necessary in the Postprocessor. This recovery will generate the nodal stress and strain from the modal displacement and finite element information. For a modal flexible body, additional output is reported as follows.

Figure 3.187: Definition of additional outputs of Modal FE body

Parameter	Symbol	Description	Dimension
Modal_Coordinate		The modal coordinate which is used to calculate an elastic force for a flexible body in Equation 5–135 in the Motion Theory Reference. [For Mode]	For Position: Mass*Length For Angle: Mass*Radians
Modal_Velocity		The modal velocity which is used to calculate a damping force for a flexible body in Equation 5–136 in the Motion Theory Reference. [For Mode]	Mass*Length/Time
Modal_Acceleration		The modal acceleration which is used to calculate an inertia force for a flexible body in Equation 5–137 in the Motion Theory Reference. [For Mode]	Mass*Length/Time^2
