The Auto Contact dialog helps you define the *CONTACT PAIR and *TIE keywords along with the corresponding *SURFACE cards.
Auto Contact is functionality within the Abaqus user profile that allows you to quickly and easily create interactions between several parts of your model. Based on a proximity distance, Auto Contact will search the model and automatically define surfaces from identified components. The interactions and surfaces are placed into a temporary Auto Contact browser, where you can review the pairs and make adjustments as needed.
Two types of interactions can be created by the auto contact functionality:
| • | *CONTACT PAIR: Definition of pairs of surfaces, which can contact or interact during an analysis. When selecting this type of interaction, you must also specify the surface interaction properties. |
| • | *TIE: Definition of constraints and interactions between pairs of surfaces. No surface interaction definition is required. |
Do not split interfaces between two components checkbox
When enabled, AutoContact will only create one contact pair or tie contact, even if components are within proximity distance in several places.
If disabled, AutoContact will create separate interfaces (CONTACT PAIR or TIE), if common surfaces between two components are not fully connected.
For example:
The yellow and red brackets are a component each and touch each other in two unconnected areas.
With the option disabled both contact areas would result into a separate contact pair/tie definition, whereas with the option enabled (only one contact pair definition is created by the algorithm).
The Auto Contact dialog contains the following buttons:
Find |
Searches the model for interacting components. |
Cancel |
Closes the Contact Pair dialog without updates. |
Remove Selection icon |
Removes selected components from the table. You can use the CTRL and Shift key to select multiple items in the table. |
Review Selection icon |
Highlights the selected component in the graphic area. All other components are grayed out. You can use the CTRL and Shift key to select multiple items in the table. Right-click to return the model to normal display. |
