Hello, i have attached baffles between blocks and after vmerg with extremely small tolerances, the warnings are baflle # only attached to one cell, will be ignored

How to proceed ?

Maybe the problem is that baffles can only be at 1:1 cell face matches, they can't act like couples. If you were trying to put a baffle where the cell faces didn't match up 1:1, I can see how that might make a vmerge fail to merge the faces and so make the baffles invalid.

yes baffle can only be valid for node to node connection.

thank you so much, i should really think more )
