Restrains partial or complete cylindrical faces in the 3 cylindrical degrees of freedom. If an input is empty, the corresponding degree of freedom will be unrestrained.

### Inputs

| Name       | Type                                                       | Description                                                                                      |
| ---------- | ---------------------------------------------------------- | ------------------------------------------------------------------------------------------------ |
| Boundary   | [Boundary](../../../../block-documentation/types/boundary) | The boundary entities containing the nodes to restrain.                                          |
| Radial     | [Scalar](../../../../block-documentation/types/scalar)     | Restraint in the radial direction from the axis.                                                 |
| Tangential | [Scalar](../../../../block-documentation/types/scalar)     | Restraint in the tangential direction about the axis.                                            |
| Axial      | [Scalar](../../../../block-documentation/types/scalar)     | Restraint along the direction of the axis.                                                       |
| Axis       | [Axis](../../../../block-documentation/types/axis)         | This is an optional entry for an axis that defines the cylindrical directions for the restraint. |

### Outputs

| Type                                                                                 |
