34.2.7 Mesh/Polyhedra/Convert Domain

The Mesh/Polyhedra/Convert Domain menu item is used to convert all 3D meshes (except pure hex meshes) to polyhedral cells. See Section  6.7.1 for details.

Conversion of a mesh to polyhedra only applies to 3D meshes that contain tetrahedral and/or wedge/prism cells. Hexahedral cells remain unchanged during conversion
