      Sometimes it is required to change the cell zone or boundary zone ID, for example while exporting a large geometry case to Ensight Gold which has a limitation on the zone ID values, at 65000. The face/cell zone ID can be changed in Fluent as well in Fluent Meshing. The way to change the ID in Fluent is to use the below TUI command: (set-thread-id (%get-thread-by-id id-to-change) newid) For example, if you want to change the ID of a zone numbered 65001 to 10, the command will be: (set-thread-id (%get-thread-by-id 65001) 10) Once executed successfully, you will notice that the ID displayed in corresponding zone pane has changed to the value that you set. The face/cell zone ID can be changed in Fluent Meshing as follows. Start Fluent in the meshing mode. Then you can use the following TUI: for Face Zones: /boundary/manage/ID For Cell Zones /mesh/manage/ID For each command you have two arguments you need to give which are a) the current zone ID you wish to change b) the new zone ID you wish to change to To see IDs of all face zones at the same time, you can go to Boundary - Manage in Fluent Meshing, select all Face Zones and List. Similar for Cell Zones. Once changed in Fluent Meshing, new IDs will be transferred into Fluent.
