31.3.20 Define/Grid Interfaces...

The Define/Grid Interfaces... menu item opens the Grid Interfaces panel.

Grid Interfaces Panel

The Grid Interfaces panel allows you to define grid interfaces for use with sliding meshes (see Section  9.5.3) or multiple reference frames (see Section  9.3.3), or for meshes with non-conformal boundaries (see Section  5.4).

Grid Interface
contains a text entry box in which you can set the name of the grid interface, and a list from which you can select an existing grid interface.

Interface Zone 1, Interface Zone 2
contain lists from which you can select the two interface zones that comprise the grid interface, and informational fields that show the name of the zone you selected in each list. (You cannot edit these fields; the name in this field will be the name of the zone you selected in the list below it.)

Interface Type
contains options related to the interface type.

indicates (if enabled) that the grid interface is periodic.

indicates (if enabled) that the interface lies between a solid zone and a fluid zone.

Boundary Zone 1, Boundary Zone 2
display the names of the wall boundary zones that FLUENT creates during the creation of a non-periodic grid interface. If the two interface zones overlap completely, then there will be no faces outside the intersection region; in such cases, no wall zones will appear in the Boundary Zone 1 and Boundary Zone 2 fields.

Interface Wall Zone 1, Interface Wall Zone 2
display the names of the wall interface zones (e.g., wall-4, wall-4-shadow), which are created if the Coupled option is on.

creates the specified grid interface (and gives it the name specified under Grid Interface).

deletes the grid interface selected under Grid Interface.

lists information about the selected Grid Interface. When you click on this button, FLUENT will report (in the console window) the two interface boundaries and all new zones that were created (i.e., interior, wall, or periodic zones).
