Errors in fixing the surface mesh repair
 

Hi there. I'm using StarCCM+ for my turbulence model. A small cube is placed inside a computational domain. I've attached a picture of my model. The problem is the base of the cube and the base of the domain are overlapping each other. I tried every possible way I know to fix this, it keeps showing me that manifold edges and piercing faces are found. I also tried the merge/imprint function but that doesn't help as well. Can somebody please help me out with this as I really want to get this thing running. Thanks so much in advance.

Hi Aditi,

It would not be necessary to fix those as you would end up wrapping the outer surfaces of the cube. It should just be fine if you leave it overlapped.
