# Export FE Mesh to CFD

Exports an FE mesh and optional CFD boundary zones to an external CFD file format.

| Mesh       | [FE Mesh](../../../../block-documentation/types/fe-mesh)                | The mesh to export.                                                                                                                                                     |
