In Mechanical, Contact corresponds to Base Geometry and Target to Action Geometry.
When creating a contact between rigid and flexible bodies, define contact on the flexible side and target on the rigid side.
If you do not create Contact Properties, the parameters are set to default values.
| Motion Stand Alone | Motion ACT | |
|---|---|---|
| Base (Contact) | Rigid (Faceset) | Flexible Behavior |
| Action (Target) | FE (Patchset) | Rigid Behavior |
When performing eigenvalue analysis in a system with Contact Regions of the type, only the stiffness in the normal direction at contact regions is reflected in the system matrix. The stiffness in the tangential direction is not considered.
