Which version are you using? In the 2021R1 release the System Coupling log file will print information about the physical extents of both interfaces. This can give you an idea if one geometry is scaled accidentally.nYou can also try running the case for one timestep to get the System Coupling EnSight results for the interfaces. You can then view these in EnSight to see why the overlap is 0%. nMore on System Coupling results in EnSight here: here:n
