About Analysis Cases

Analysis cases are containers for different combinations of steps and simulation features. You can create multiple analysis cases within a simulation scenario (except in thermal simulations). Each analysis case contains its own sequence of steps as well as simulation features such as initial conditions, restraints, loads, and output requests.

Creating and Duplicating Analysis Cases

As you work in a scenario app, any new features you create are added to the active analysis case. Features cannot be shared between different analysis cases. However, you can duplicate analysis cases to make a copy that you can modify rather than recreating features in a new analysis case.

Note: You cannot duplicate coupled analysis cases, such as a thermal analysis case and structural analysis case in a thermal-structural simulation.

The active analysis case is shown in the context selector in the work area, as in this example from a structural simulation:



You can delete analysis cases from the tree by using the context (right-click) menu.

If you export a structural simulation to an Abaqus input (.inp) file, each analysis case is saved in a separate file; for example, 

MyScenario_StructuralAnalysisCase.1.inp
MyScenario_StructuralAnalysisCase.2.inp

You must associate a finite element model with each analysis case by using Create Finite Element Model or Select Finite Element Model.

When you create an analysis case, you can also include model change data with restart data to continue an analysis. This option is not available for analysis cases that contain an explicit dynamics step.

When you choose Simulate from the action bar, you can run the simulation job for any or all analysis cases in your simulation.

For structural analysis cases that do not include explicit dynamic steps, you can also enable model change activation for contact pairs. This option reactivates the contact pairs from the selected structural analysis case in a subsequent restart analysis case.
