ggi for non-overlaping interfaces (OpenFOAM-2.2)
 

Hello All,
I hope your day is going well.
I am trying to solve a mesh problem as described in
http://powerlab.fsb.hr/ped/kturbo/OP...asakHrvoje.pdf
(case 2, dump case, mesh in the pic). Basically, it is a small-area nozzle connected to a big dump. Part of the interfaces are overlaping, the rest of the surface is supposed to be converted to wall. It seems using GGI interface could solve this problem. Could anyone point me to any tutorial if there exists one? or give me some instruction how I should treat such faces? I do not have much experience with OpenFOAM, especially the higher-versions. Any advice is welcome.

Thanks,
Xinyu
