Creating Mesh Interface Between Different Zones

When setting up mesh interfaces, what are the different zones created by Ansys Fluent software?

When creating a mesh interface between 2 zones, Ansys 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 Ansys Fluent User Guide.
