Emergency-- Structured Meshing of Bifurcation
 

Hi my friends, I want to mesh a bifurcation. Bifurcation is a unit of human lung that composed with three pipes with different diameter. Now I am in trouble because I could not build a structured meshing in this geometry and this step is very important for me. Can you help me? If everyone wants to see this geometry I can send file.
