I am using snappyHexMesh generating grid but it always has some very strange grid at the geometry surface. Can any expert tell the reason and solution? Thanks.

I used snappyHexMesh to generate mesh. I got this result as attached that the snap function cannnot capture the geometry (blue parts) accurately. Can any expert tell the reason and solution? Thanks.

The problem can be solved in some degree by adjust the snap controls setting.

I encountered a new problem that grid at some corners of the geometry has been very weird. Can any expert tell the reason and solution?
Thanks

Even refining the grid near the geometry would not solve this problem.
