The time-dependent analysis is performed for a load case to which the analysis type 'Time-Dependent Analysis' is assigned. In the Load Cases and Load Combinations tabs of the 'Load Cases and Combinations' dialog box, you can assign the analysis types and define time-related parameters.
Select the relevant load case on the left in the 'List'.
Categories
If the 'Time-Dependent Analysis (TDA)' add-on is activated in the Model's Base Data, the analysis type Structural Analysis | Time-Dependent Analysis (TDA) is available for selection in the list. Assign this type to each load case for which a time-dependent analysis is to be performed. You can adjust the calculation in the Structural Analysis Settings.
