Limitations for Localization
Some areas of the Fluent 2024 R2 GUI are not completely translated including:
Drop-down menu/list items
Quick search results
Pop up messages
Graphics window titles and labels
Object names (boundary conditions, graphics objects, and so on)
Interface (GUI labels) for items without meaningful Japanese/Chinese/Korean equivalents, such as X, Y, Z, Cp, OK, and so on
The Console
Important: Localization of the Fluent workspaces is a Beta-level exposure, meaning that it has not been fully tested or validated. The workspaces include Aero, Icing, Material Processing, and Post-Analysis (which is itself Beta level).
