Inserting a New Static Linear Perturbation Step
Inserting a static linear perturbation step within the Simulation History indicates that a static linear perturbation solution procedure should be used for the computation of the system response to applied static loads under given constraints. You can create environmental specifications (for example, boundary conditions and loads) within the step. Static linear perturbation steps are available only in a Nonlinear Structural case. They can be defined in new cases or in cases that contain other general static or static linear perturbation steps. They cannot be defined in an Explicit Dynamic case or in a Thermal case. See Linear Perturbation Steps, and Step Sequence Restrictions for more information.
This task shows you how to insert a new Static Linear Perturbation step in a Nonlinear Structural case.
Select Start>Analysis & Simulation>Nonlinear Structural Analysis from the menu bar to enter the Nonlinear Structural Analysis workbench.
From the New Analysis Case dialog box, select Nonlinear Structural Case.
To create an additional Static Perturbation step, do either of the following:
To append a new Static Perturbation step to the end of the Simulation History, click the Static Perturbation Step icon
.Tip: Alternatively, you can select Insert>Static Perturbation Step from the menu bar.
To insert a new Static Perturbation step between two existing steps in the Simulation History, right-click the step object in the specification tree after which you want to create the new step, then select Insert Step Below>Static Perturbation Step from the menu that appears.
You can change the step identifier by editing the Step name field. This name will be used in the specification tree.
Enter a description for the step in the Step description field.
Click OK when you have finished defining the step.
The Static Perturbation Step objects set contains a default Field Output Request object in a Field Output Requests objects set. See Requesting Results for more information.
