hello,everyone.
In the help-document of GGI (General Grid Interface) Connections, GGI connections permit non-matching of node location, element type, surface extent, surface shape and even non-matching of the flow physics across the connection.
So i think the GGI Connections is the overlapping surfaces, and if the size of the connection region for one side is different to the second side, the connection will be automatically made between the mutually overlapping surfaces.
And then i define a solid-solid interface.but the side_1 is bigger than the side_2.
But at the ANSYS CFX Output File (GGI Runs), it shows:

Domain Interface Name : Domain Interface 7
Non-overlap area fraction on side 1 = 7.21E-05
Non-overlap area fraction on side 2 = 6.44E-08
Domain Interface Name : Domain Interface 6
Non-overlap area fraction on side 1 = 0.00E+00
Non-overlap area fraction on side 2 = 5.00E-01
Domain Interface Name : Domain Interface 5
Non-overlap area fraction on side 1 = 0.00E+00
Non-overlap area fraction on side 2 = 0.00E+00

So am i wrong ? Can i dedine a interface that the side_1 is bigger than the side_2 ?
