Status Terms

The propagation and activation statuses of an object appear in the dialog box used to create or edit the object; click More to access this information.

Propagation Status

You cannot change the propagation status of an object. Nonlinear Structural Analysis and Thermal Analysis use the following terms to describe the propagation status of objects in particular steps:

Created

The object was created and becomes active in this step. The introduction of a prescribed condition in a step depends on the amplitude variation associated with that step. For more information, see Amplitudes.

Modified

The definition of the object has been modified in this step. The variation of a prescribed condition over the course of the step depends on the amplitude variation associated with that step.

Propagated

The object was created or modified in an earlier step of the analysis and continues to be active in this step.

An initial temperature field does not propagate.

Activation Status

You can change the activation status of an object by right-clicking on the object in the specification tree and selecting Activate/Deactivate. Nonlinear Structural Analysis and Thermal Analysis use the following terms to describe the activation status of objects in particular steps:

Active

The object is active in this step (created, modified, or propagated).

Inactive

The object has been deactivated in this step or in a previous step. It will remain deactivated in all subsequent steps until you reactivate it. Deactivating an object in the step in which it was created effectively suppresses the object for the entire analysis, which means it is not written to the input file and is treated as a deleted object. The point in the step at which a prescribed condition becomes inactive depends on the amplitude variation associated with that step. For more information, see Amplitudes.

You cannot deactivate fields; an inactive status for a field means that the field has been reset to the value specified in the initial step. The point in the step at which an object resumes its initial value depends on the amplitude variation associated with that step. For more information, see Amplitudes.
