# CFD Boundary on FE Mesh

Identifies a CFD boundary on an FE mesh which then can be exported to an external CFD file format.

### Inputs

| Name     | Type                                                       | Description                                                                                            |
| -------- | ---------------------------------------------------------- | ------------------------------------------------------------------------------------------------------ |
| Boundary | [Boundary](../../../../block-documentation/types/boundary) | Element set on which the CFD boundary should be applied.                                               |
| Type     | CFD Boundary Enum                                          | CFD boundary type. Parameters of the boundary condition are specified in the external CFD application. |
| Name     | [Text](../../../../block-documentation/types/text)         | The name of the boundary zone in the exported mesh file.                                               |
