6.3.10 CFX Files

You can import 3D CFX files, such as definition ( .def) and result ( .res) files into FLUENT, using the File/Import/CFX menu item, as described in Section  4.11.3. The fe2ram utility is used as the import filter, which can be used as a stand-alone to obtain a FLUENT mesh file. See Section  6.3.11 for information about fe2ram.

The 3D element set corresponding to zones/domains present in these files are imported as cell zones in FLUENT. They may contain tetrahedral, pyramidal, wedge, and hexahedral elements. The boundary zones in these files are a group of faces with a boundary condition name/type and are imported as face zones with the boundary condition name/type retained in FLUENT. The following boundary condition types are retained:

The boundaries of type Interface may be conformal or non-conformal. If they are non-conformal, they are retained. However, conformal interfaces contain coincident nodes which are merged and changed to type Interior. For some cases, for the merge to work correctly, the merge tolerance may need to be adjusted. Alternatively, FLUENT's fuse thread functionality can be used to merge the conformal interfaces.
