separated pipe meshing
 

Dear fellow Foamers,

I'm begineer of OpenFOAM and CFD. I'm undergraduate student of chemical engineering. And I'm trying to mesh a pipe separated in blockMesh.
But I don't know how to start meshing of that. So if you are able to meshing separted pipe(like Y shape pipe), I earnest request show me meshing file or explain how to make meshing.
