Can anyone please tell me how to carry out boolean operation with ICEM CFD? I have used GAMBIT previously, but trying to switch to ICEM. I understand ICEM is a surface based modeler, but I was thinking there might be a way around it.

My geometry is made up two concentric pipes, in which fluid flows between the inner and outer pipes known as the annulus. I wish to me render flow through the annulus by subtracting the inner pipe from the outer to form a single annular volume, then use a volume mesh with good refinement towards the walls.

Please i need help really fast. You can also refer me to the exact part of the ICEM CFD tutorial guide where an example of similar volume meshing can be found.

Thank you.
