mesh a Y-section (circular pipe) with all Hex elements?
 

Dear CFD experts,

I am wondering if someone can point to me examples of decomposing a Y-section pipe (circular cross section) into multi-blocks so that I can mesh it with all hex elements. For the Y, I am looking looking for both same diameter coming to the Y and different diameters coming into the Y.

Thanks!
