  Scalar, Direction Component Enum, Boundary, Load case
</h2>

Define a displacement constraint for a topology optimization process.

### Inputs

| Name | Type | Description |
| - | - | - |
| Displacement | [Scalar](../../../../block-documentation/types/scalar) | The displacement limit. The magnitude of the displacement will be less than or equal to this value. |
| Direction | Direction Component Enum | The direction which the constraint applies to. |
| 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. |

### Outputs

| Type |
| - |
| [Design Constraint](../../../../block-documentation/types/design-constraint) |
