| Displacement | [Scalar](../../../../block-documentation/types/scalar)                              | The displacement limit. The magnitude of the displacement will be less than or equal to this value.                                                                             |

| Boundary     | [Boundary](../../../../block-documentation/types/boundary)                          | The FE Boundary that defines the nodes where the displacement response should be measured. Any node in this boundary should displace less than or equal to the specified value. |
| Load case    | [Boundary Condition List](../../../../block-documentation/types/boundary-condition) | The load case for the displacement constraint. A load case is defined as a list of boundary conditions.                                                                         |
