Analytical Rigid Surfaces
The Abaqus solver offers the flexibility of modeling rigids as surfaces using primitive geometry.
Simplicity of modeling is the primary advantage of using this feature.
- can be 2D or 3D
- can be swept or revolved geometry
- can be used with the small-sliding, or finite-sliding mechanical contact formulations
- should be oriented in such a way that the surface's outward normal of the surface points toward any part it may contact
- is associated with a node, known as the rigid body reference node, whose motion governs the motion of the surface
- Selecting/defining a local system
- Choosing 2D or 3D and within 3D sweep or revolve
- Choosing lines or a node path to define the feature in the chosen local plane to complete the analytical rigid surface set-up
