Simulation Navigator for Response Dynamics

The Simulation Navigator main panel includes several nodes used specifically for Response Dynamics. See Simulation Navigator overview for information about other areas of the Simulation Navigator.

The picture below shows the Simulation Navigator as it may appear after you solve the SOL 103 - Response Dynamics solution, add an event and an enforced motion excitation, and evaluate the response function and an acceleration contour result.

Most of the Response Dynamics features are accessible using right-click commands on the navigator nodes.

Solution 1 Temperatures Simulation Objects Constraints UserDefined(1) EnforcedMotionLocation(1) Solution 1 Temperatures Simulation Objects Constraints UserDefined(1) EnforcedMotionLocation(1) Solution node The Solution node for Response Dynamics contains the loads and boundary conditions for your model. Constraints such as Enforced Motion Locations and loads such as Nodal Force Locations specify the locations for your excitation loads and determine the types of modes the solver generates. See FE model and boundary conditions for more information.

These loads also affect the calculation of the dynamic modes. See FE model and boundary conditions for a description of each subcase type.

The note “Obsolete” appears next to this node when a change has occurred in your model that requires the solution to be solved again.When you click the Normal Modes, Residual Vectors, or Excitations node, the Response Dynamics Details View subpanel displays important information about each normal mode or about each defined excitation. See Response Dynamics Details View subpanel (Simulation Navigator) for more information.
