Overlap taking place

I am simulating the slope, but there are some serious overlapping taking place.




I already used ‘block delete’ to delete the overlapping blocks.Now I am thinking is there any FISH codes to remove this overlapping problems other than delete blocks?
I also tried using block tolerance 1e-3 and the edge tolerance 1e-8 to reduce the overlap. Even the overlapping blocks size are large.

What else can be done? Thank you

Ray,
I am working on it. It took many hours to re-run the code.
Can you tell me at about what number of cycle the overlapping is happening, I can go from there to verify the solution to this problem.
