A pipe with extruded mesh contacting a tet-meshed block. The element faces on the circular end of the pipe that contacts the block are extruded down the length of the pipe.
This heat sink is extrusion meshed:
It is immersed in air that is tet meshed. The nodes do not line up, but the two parts are automatically linked computationally:
A rectangular box is extrusion meshed. There are three extrusion directions available for this box, and the Extrusion dialog allows selection of the desired one.
