Changing Face and Cell Zone IDs using TUI

How face and cell zone IDs can be changed using TUI?

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 Ansys Fluent as well in Ansys Fluent Meshing.

The face/cell zone ID can be changed in Ansys Fluent Meshing as follows.

Start Ansys 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 Ansys Fluent.
