" your geometry has a hole. Do you want to repair it?"
 
I try to meshing with ICEM CFD. After meshing i get message like this " Your geometry has a hole. Do you want to repair it?. Any body can explain it. Thank you

Octree Process...
 
The octree tetra process is "top down" and requires a geometry that is closed (at least relative to the mesh size). At one point in the process, it does a flood fill to determine containment (so it can separate inside from outside). If there is a hole some where, then this separation is not possible and it gives you the opportunity to fix it by closing the hole at the mesh level. Look for a connection of yellow edges (single edges) representing the hole. You can fix it with mesh edit tools here or you can go back and fix the geometry in that area and run the mesher again.

Look up "Octree" or "Flood fill" in the help for more details.
