At the start of the simulation, all GGI connection conditions are processed. This may require the computational effort of the order of a single iteration or timestep of the flow simulation. If a GGI connection condition is found to contain non-overlapping portions, the percentage of the area of each side that is non-overlapping is reported. This is a useful diagnostic, and should be reviewed to confirm that the expected amount of non-overlapping area has been detected.

Residual diagnostics will be reported for each set of connected domains having the same physical type. For example, the mass and momentum equation residuals will be reported independently for each flow passage.

Flows across GGI interfaces will be reported in flow summary diagnostics. Changes in GGI flows will occur in various situations. For example, momentum flows change as they undergo rotation at rotational periodic GGI connections. All transport equation flows, including the mass equation, change for the case of pitch change at a frame change GGI connection, as well as the energy equation flows as conservation changes from absolute frame to relative frame energy components. Forces are also reported in the momentum flow balances at contiguous and periodic GGI connections, for cases having non-overlapping portions of the interface.

Various quantities such as ranges of dependent variables, locations of maximum residuals, and so on, are reported at the end of the simulation on a per-domain basis.
