It isn't a big problem. you cannot comment the boundary list. I edited it for you in red.
Also note that, it just one mesh cell for each block. You have add more cells in x and y directions and it should be consistent with across the blocks boundaries. Otherwise, you will have to use the mergePatchPairs option. Bw, Hassan Quote:
