7.1.4 Setting Cell Zone and Boundary Conditions

In ANSYS FLUENT, boundary conditions are associated with zones, not with individual faces or cells. If you want to combine two or more zones that will have the same boundary conditions, see Section  6.8.1 for information about merging zones.

To set cell zone and boundary conditions for a particular zone, perform one of the following sequences:

1.   Select the zone from the Zone list in the Cell Zone Conditions or Boundary Conditions task page.

2.   Click the Edit... button.

or

1.   Choose the zone in the Zone list.

2.   Click on the selected zone type from the Type drop-down list.

or

1.   Double-click on the zone in the Zone list.

The dialog box for the selected cell or boundary zone will open, and you can specify the appropriate conditions.

If you are using one of the general multiphase models (VOF, mixture, or Eulerian), the procedure for setting conditions is slightly different from that described above. See Section  24.2.9 for details.
