33.8.1 Create/Edit Mesh Interfaces Dialog Box

The Create/Edit Mesh Interfaces dialog box allows you to define mesh interfaces for use with sliding meshes (see Section  11.2) or multiple reference frames (see Section  10.5), or for meshes with non-conformal boundaries (see Section  6.4).

Controls

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

Interface Zone 1, Interface Zone 2   contain lists from which you can select the two interface zones that comprise the mesh 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 Options   contains options related to the interface type.

Periodic Boundary Condition   allows you to create a non-conformal periodic boundary condition interface.

Periodic Repeats   is relevant when you have two zones coming together, such as a rotor and stator. When the two zones move, a portion of the geometry will intersect and that will be an interior zone, but on either side of the interior, the zone is termed periodic repeats.

Coupled Wall   indicates (if enabled) that the interface acts as a thermally coupled wall.

Boundary Zone 1, Boundary Zone 2   display the names of the wall boundary zones that ANSYS FLUENT creates during the creation of a non-periodic mesh interface. If the two interface zones overlap each other, then the wall boundaries are created but with zero faces.

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 Wall option is enabled.

Periodic Boundary Condition   

Type   allows you to select a periodicity that is either Translational or Rotational.

Offset   is the offset coordinates or angle, depending on whether Translational or Rotational periodicity is selected. Note that when Auto Compute Offset is enabled, the Offset fields are not editable.

Auto Compute Offset   will result in ANSYS FLUENT finding the offset. If this option is disabled, then you will have to provide the offset coordinates or angle in the required fields, depending on whether Translational or Rotational periodicity is selected.

Create   creates the specified mesh interface (and gives it the name specified under Mesh Interface).

Delete   deletes the mesh interface selected under Mesh Interface.

List   lists information about the selected Mesh Interface. When you click on this button, ANSYS 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).
