NOTES

  1. This section defines the parameters that control the visualization of the entire model. The time step size, TimeStepSize, used in the visualization is constant and can be different from the time step size used for predicting the dynamic response of the system. If if also possible to select a frame to be used as basis the visualization; this frame can either be a fixed frame or a moving frame.
  2. For static analysis, it is possible to compute eigen modes, see section~\ref{StpCtrl: Eigen Analysis} of the system. In the visualization phase, these eigen modes can be animated. Since the magnitude of an eigenmode is undetermined, a scaling factor seig will be used to scale their maximum amplitude (Default value: 0.2). Each eigen mode will be animated for Ncyc cycles, using Fcyc frames per cycle.
  3. The visualization phase enable the representation of a number of vector fields that are superimposed to the instantaneous configuration of the system. The visualization of a specific vector field is enabled by defining graphical parameters, see section~\ref{GrfParam} for that object. Specific objects allow various VfdType, chosen from the following options
    • AERODYNAMIC_FORCES Visualization of the aerodynamic forces along lifting lines.
    • AERODYNAMIC_MOMENTS Visualization of the aerodynamic forces along lifting lines.
    • ANGULAR_VELOCITIES Visualization of the angular velocities of structural components such as beams, cables, membranes, rigid bodies or shells.
    • CURVATURES Visualization of the curvatures of structural components.
    • FORCES Visualization of the forces in structural components.
    • MOMENTS Visualization of the moments in structural components.
    • STRAINS Visualization of the strains in structural components.
    • VELOCITIES Visualization of the velocity in structural components.
    The vector field scaling factor, svfd, determines the graphical magnitude of the vector field during the animations (Default value: svfd = 0.125).
  4. It is possible to attach comments to the definition of the object; these comments have no effect on its definition.
