Description: The new model change interaction type allows you to deactivate and reactivate regions during an analysis and allows you to indicate that model change interactions may be present during a subsequent restart analysis.

A new model change interaction allows you to deactivate and reactivate elements, skins, stringers, and geometry for a model. You can also deactivate and reactivate elements, skins, and stringers for an orphan mesh. This interaction type is available for all Abaqus/Standard analysis procedures except for the static, Riks procedure and linear perturbation procedures. Stress/displacement elements can be reactivated in a strain-free state or with strain. You can request detailed model change information to be written to the message file for an Abaqus/Standard analysis. The model change interaction editor is shown in Figure 10–2.

A new toggle on the surface-to-surface contact and self-contact editors allows you to deactivate and reactivate contact pairs in analysis steps. Abaqus/CAE allows you to control the visibility of deactivated regions in the Visualization module. The display of the deactivated regions is dependent on the status of the new visibility toggle and on the plot state used in the viewport.
