Deformation Animation
During animation, by default, the nonlinear flexible body will have color contour plotting that represents the deformation. This deformation is the displacement of each node relative to the "datum node" specified in the nonlinear flexible body modify dialog box. By default no "datum node" is selected and Adams View considers the deformation to be relative to the origin of the flexible body (its local body reference frame, LBRF) which, for nonlinear flexible bodies, is the origin of the model and will not move with the flexible body during the simulation. For more details see the description of the "datum node" in the dialog box help. Note that when animating deformation while the analysis is still running, the color scale can only take into account the maximum deformation to that point in the simulation; so, the colors may appear differently when animating partial results as opposed to when animating a completed analysis.
Note that the animation of nonlinear flexible bodies is enabled by the .op2 file generated during the analysis. It is referenced by the .res file not the .gra file. Therefore animation of nonlinear flexible bodies requires the .res file and is not supported by analyses composed solely of a .gra file.
