Hi,
I am working on heat transfer from a buried pipe and I am simply representing it as a circle in a rectangle (2D) in Gambit, I am confused on how to subtract the circle from the rectangle.
When I subtract the circle and retain it, when I check my edges I find an extra edge created, so now I have 2 edges representing the pipe.
Otherwise, when I subtract the circle from the rectangle and do not retain it, I no longer find the face representing the circle, this seems right to me but I just wanna make sure I am on the right track.
Also I wanna make sure I do not have to mesh the circle face right?
Any help will be appreciated.
Thanx in advance.

-mAx- will become famous soon enough
your second attempt seems to be the right one (disk not retained), especially if physics in the disk isn't an interest
