When you generate a mesh using the meshing mode of Ansys Fluent (which was previously a stand-alone program named Fluent Meshing) or export a mesh from Ansys Meshing in the Fluent format, the mesh information is written as an Ansys Fluent mesh (that is, a .msh file). You can read such a .msh file directly into Ansys Polydata or Ansys Polyman, as described in Reading Files Directly and Importing a Mesh File, respectively.

Ansys Meshing and the meshing mode of Ansys Fluent allow the generation of surface (boundary set) and volume (subdomain) topologies. The names of the different topological entities (subdomains, boundaries, and PMeshes) will transfer to the Ansys Polyflow mesh file. It is a good practice to provide mnemonic names that help to easily identify the different geometric entities. Note that the names are limited to a maximum of 12 characters, and that the names of PMeshes must start with pm in lower- or uppercase letters (for example, pm1, PMA, or PmScreen1).

When working with Ansys Fluent meshes in Ansys Polyflow, note the following limitation: contrary to Ansys Fluent, Ansys Polyflow applications cannot handle polyhedral elements. If such elements are found, an error message will inform you that the translation has been aborted.
