I don't know. when I use common meshing, the boundary condition will be like that. the interface part has another name such as coil-contact-region-src has another name which is wall-20 and so does the other interface.

But when I use fluent special meshing (fluent with meshing), the boundary condition naming becomes simpler, as in the following picture

although the results between the two boundary conditions are still the same. still not in accordance with validation. so is there an error in the boundary conditions or in other parts?
