Step sequence restrictions

When you select StepCreate from the main menu bar, a Create Step dialog box appears in which you can specify the procedure type for the step that you are creating. Similarly, when you select StepReplace from the main menu bar, a Replace Step dialog box appears in which you can specify a new procedure type for an existing step. The selection of procedure types in the Create Step and Replace Step dialog boxes depends on the following:

  • The model type.

  • The procedures that you have already associated with existing steps.

  • The position of the new or replaced step in the analysis step sequence.

For example, when you create the first step in an analysis, you can choose from a list of valid procedure types; both Abaqus/Standard and Abaqus/Explicit procedure types appear in the list. However, once you have created the first step, the list of valid procedure types in the Create Step dialog box will change to include only those procedures that are compatible with the first step. For example, if the first step is an Abaqus/Standard step, Abaqus/Explicit procedures no longer appear in the list.
