🟩 FEA Friday- Getting started with "Contact" Connection

Connections are defined as interactions between components in your assembly.

Connections are of below types:

  • Bolts
  • Contacts
  • Pins
  • Rigid Connections
  • Springs


Contacts

In an assembly including multiple components, the interactions between components are defined by contacts.

Contact is essentially the definition of parts interacting with one another and/or itself

Contact features let you describe how surfaces from different part bodies affect one another when they contact during a simulation.


Types of contacts:

  • Bonded
  • Sliding
  • Thermal

Contact Initializations

About Contact Initializations

Contact initializations are automatic adjustments that can correct small gaps or overclosures between general contact surfaces before the simulation starts.

Contact Tools (📢 Click on each title below to know in detail)

About Contact Tools

Contact tools enable you to identify where surfaces of your model are contacting, disconnected, or intersecting. This information helps you identify where you might need to define contact or connections to ensure a successful simulation.

Locating Contacting Bodies

You can use the contacting parts tool to locate any touching bodies in your model. This tool helps you identify where you might need to define contact or connections to ensure a successful simulation. Any geometric entities that align and just touch one another are listed and can be highlighted.

Locating Disconnected Bodies

You can use the disconnected bodies tool to determine if any bodies in your model are tied together by surface-based contact. This tool helps you identify where you might need to define contact to ensure a successful simulation. Any geometric entities that are disconnected in the model are listed and can be highlighted.

Locating Intersecting Bodies

You can use the intersecting parts tool to locate any clashing bodies in your model. This tool helps you identify where you might need to define contact or connections to ensure a successful simulation. Any geometric entities that overlap and penetrate one another are listed and can be highlighted.

General Contact

When you define general contact, the app includes small-sliding interactions in the general contact definition automatically

Surface-Based Contact and Bonded Contact

The topics in this section provide conceptual information about using bonded contact and surface-based contact as well as a step-by-step description of how to define these features in your model.
