strider Guest Posts: n/a	I similated a flow threw a serie of rectangular pipes including different meshes. I set GGI interfaces between those meshes and the simulation converged. The thing is that when I checked the results, I observed great difference of energy level on each side of the interfaces, even if it's physically the same plane i'm checking. It seems that there is a «numerical» head loss across the interfaces. Am I wrong? Why does it occurs? Can I solve that? Any help would be very apreciated. Thanks strider
