You can use the Interaction module to define and manage the following objects:
Mechanical and thermal interactions between regions of a model or between a region of a model and its surroundings.
The interface region and coupling schemes for an Abaqus/Standard to Abaqus/Explicit co-simulation.
Analysis constraints between regions of a model.
Assembly-level wire features, connector sections, and connector section assignments to model connectors.
Inertia (point mass, rotary inertia, and heat capacitance) on regions of the model.
Cracks on regions of the model.
Springs and dashpots between two points of a model or between a point of a model and ground.
