Interactions Section

Interactions define the simulated responses that occur when different regions of a model come into contact with each other.

Interactions are step-dependent actions.

Contact Detection
Identifies contacting surfaces and creates surface-based contact between them.
See Using Contact Detection.
Surface-based Contact
Specifies contact between two surfaces.
See Defining Surface-based Contact.
General Contact
Specifies the contact behavior between all components in a model.
See Defining General Contact.

Note: This option is not available in thermal simulations.
Contact Initialization
Adjusts general contact surfaces to remove small gaps or overlaps.
See Defining Contact Initialization.

Note: This option is not available in thermal simulations.
