Overset cannot identify right acceptor and donor
The overset cannot run properly when the createBaffles utility was used. There comes a very large velocity abnormally around the baffle. I guess it was caused by the wrong acceptor cells chosen.
The first page is overset mesh. The yellow bar is the baffle created by the createBaffles utility.
The second page is background mesh. It can be seen that the baffle wall is detected and marked as HOLE.
However, the interpolation cell around baffle on overset grid cannot find any donors from background mesh.
