Creating an Abaqus Analysis Case
This task shows you to how to enter the Nonlinear Structural Analysis workbench and create an analysis case containing a general static step.
Select Start>Analysis & Simulation>Nonlinear Structural Analysis from the main menu bar.
The New Analysis Case dialog box appears with the default Nonlinear Structural Analysis type selected.
Click OK in the New Analysis Case dialog box to enter the Nonlinear Structural Analysis workbench.
Warning: Do not select Keep as default starting analysis case in the New Analysis Case dialog box.
A .CATAnalysis document named Analysis1 opens. A link exists between the .CATPart and the .CATAnalysis document. In addition, the standard structure of the Analysis Manager specification tree is displayed.
The Nonlinear Structural Case objects set contains a Simulation History objects set with an Initialization step and a Static Step objects set, a Jobs objects set containing a default job, and empty Display Groups and Analysis Case Solution objects sets. The Simulation History will contain a description of the environmental influences on the model, which generally vary as a function of time over a period defined by the user. (See Specification Tree for more details on the specification tree.)
To edit the static step created with the analysis case, double-click on the Static Step–1 objects set in the specification tree under the Simulation History objects set for the current analysis case. (The current analysis case is the one most recently created or edited; it is underlined in the specification tree.)
Abaqus for CATIA V5 opens the Static Step dialog box.
Note: To create a new static step, you can click the General Static Step icon
.You can change the step identifier for the Static Step 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. This description will appear in the input file that is written for this analysis.
In this example we expect that the part will deform significantly; hence, it is appropriate to consider finite deformation effects. Specify that Abaqus should account for nonlinear geometric effects in the step by selecting On for Nonlinear geometry. (See General and linear perturbation procedures in the Abaqus Analysis Guide for more information on geometric nonlinearity.)
Accept the default values for the other step controls.
Click OK when you have finished editing the step.
The Static Step objects set contains a default Field Output Request object and empty History Output Requests, Loads, Boundary Conditions, and Fields objects sets.
