This section is applicable to boundary zones only.

If you want to override the default boundary zone type assignments by using Named Selections, naming conventions have been provided for you to follow. Use these conventions when defining Named Selections in either the Ansys DesignModeler application or the Meshing application. By following these naming conventions consistently, you can ensure that Ansys Fluent boundary zone types will be assigned correctly and predictably in the exported Ansys Fluent file.

When naming Named Selections, it is best practice to specify the appropriate name from the list below exactly as shown (case-insensitive). In cases where the name shown below contains an underscore character, a hyphen is also acceptable (for example, both EXHAUST_FAN and EXHAUST-FAN will work). (Note, however, that although the Meshing application allows both hyphens and underscore characters to be used when defining Named Selections, the DesignModeler application allows only underscore characters.)

The name of each Named Selection is filtered upon export such that only allowable characters remain. Allowable characters include all alphanumeric characters as well as the following special characters:

` ! $ % ^ & * _ + - = : < > . ? /

All other characters, including spaces, are invalid. If an invalid character is used, it is replaced by an underscore (_) upon export.

In addition, the export process does allow for partial matches and special abbreviations, which are described in Zone Type Assignment.
