Hi everyone,

My question concerns probably silly issue, but I can't see the solution at the moment, so I hope you can give me some hint. What's the problem? So... I made a 2D geometry just by defining verticies, blocks (hex) and edges (because I have some splines and arcs) in one blockMeshDict file. Everything looks great, as you can see at the attached picture (sorry for the low resolution).



My blockMeshDict defines hexahedrals as shown at the schematic picture below (green lines depict borders of those hexes):



And now my fundamental question is. Should I expect that all of the hexahedrals are automatically connected one to another or should I define some patches between them or even merge them somehow?

Just as a addition I should say that I added until now two patches that I need for sure. They are inlet (top of a pipe in the middle) and outlet (on top right of a tank).
