Hi there,

I'm using sHM to create a baffle surface within a geometry of 2 cylinders of unequal diameter (image 1- baffle is green).

I have managed to get a really good mesh finally however at the interface where the baffle meets an external boundary there is a weird overlap of faces.
(Top view - baffle is the red surface in images 2, 3, 4 show this where it is not clear what is happening) While selecting the faces on the patch (image 4) one sees how several faces are overlapping each other. (however, they lie in the same plane) Has someone faced a similar issue at any point or can point me in a right direction?

There is some kind of problem during the snapping stage however I am unable to figure out what it is.
Please help !
