mesh problem
 
Hi everyone,
i have a problem with mine mesh. The geometry is a cube where inside there are a circular hole. In the summit of a cube i have a split so when i'm going to meshing the volume with a cooper schem i have an error for this split.
is there a method for meshing the volume without doing a split in lower surface of cube?
thanks for any suggeston

I would split it like this:

All faces are meshed with a structured mesh. For some of the faces (see the picture,) you need to change one vertex from "end" to "side", because the quad:map scheme requires the number of end verticies on a face to be equal to four.

the problem is showing in the second picture. i have a similar geometry, but the volume that not have the mesh in picture in my case there aren't a split so is a simple cube.
for resolve the problem i do the split this cube or there is a method for meshing without it.

Hmm, I'm not sure if I understand. In you case, does the circular hole go completely through the cube? Maybe if you posted a picture the problem would be more clear.
