When the Matching option is selected, ANSYS Fluent checks if one interface zone sits on top of the other and displays messages if there is an overlap of cell zones that are connected through a mesh interface (therefore making the interface invalid for use). Since the severity of zone overlap is different for matching interfaces and non-matching interfaces, ANSYS Fluent displays different messages accordingly.
For example, for non-matching interfaces:
When two interface zones do not match well (which could result from different mesh topologies, geometric misalignment, or the existence of large gaps), wall zones will be created on the interface. If, in such cases, you want to have only interior zones generated on the interface, it is best to use a matching interface. If the interface zones cover each other completely, and no wall zones are expected to be created on the mesh interface, it is recommended that you select the Matching option.
Note: The Matching option is also compatible with the periodic boundary condition option.
Figure 5.34: Matching Non-Conformal Wall Interfaces below shows two interface zones that do not match up well in the center -- the interface zone on the right has an inverted spike. Even with such a large mismatch, the Matching option still enables you to create an interface with only the interior zone.
Info: Interface zones overlap for mesh interface (interface-name). This could adversely affect your solution.
Likewise, for matching interfaces:
Warning: Interface zone overlaps for mesh interface (interface-name).
This could generate left-handed faces on the interface and make it invalid for use.
