當兩個interface不能完全匹配時，fluent會自動將邊界分為匹配的邊界（overlapping）和不匹配的邊界（non-overlapping）兩部分
流體與流體
- 匹配的部分，命名為 Interface Interior Zone，表示允許流體通過
- 不匹配的部分，命名為 Boundary Zone 1-non-overlapping 與 Boundary Zone 2-non-overlapping
固體與固體（或流體與固體？）
- 匹配的部分，命名為 Interface Wall Zone 1 與 Interface Wall Zone 2，並會同時創建shadow zone
- 不匹配的部分，命名為 Boundary Zone 1-non-overlapping 與 Boundary Zone 2-non-overlapping

When creating a mesh interface between 2 zones, Fluent will look at what are the overlapping and non-overlapping sections between the different sides of the interface.
If the interface connects different fluid zones, the following boundary zones will be created :
-Interface Interior Zone : this corresponds to the overlapping section through which will go the fluid flow
-Boundary Zone 1 and Boundary Zone 2 : those correspond to the non-overlapping sections for each of the connected zones
If the interface connects different solid zones (Coupled Wall), the following boundary zones will be created :
-Interface Wall Zone 1 and Interface Wall Zone 2 : this corresponds to the overlapping section, through which will occur the heat transfer, split into a wall and a wall shadow, for each of the connected zones.
-Boundary Zone 1 and Boundary Zone 2 : those correspond to the non-overlapping sections for each of the connected zones
For additional information, the interface creation procedure for non-conformal meshes is fully described in the section “Non-Conformal Meshes” of Fluent User Guide.
