How to run ICEM over parallel processor?

I want to run ICEM over parallel processing. I follow the path "Settings => General => number of processors" to assign number of the processors which I want to used by ICEM. But it doesn't work and still ICEM used just one processor.
Any idea about this issue?

It's not a bug, ICEM can use more than 1 proc only for some operations, not all the time.

What do you mean by some operations?
Why not for the all? And what is those operations?

what is it exactly that you wanna do with the multiple processors?

Since I have huge number of node in a geometry, after each modification, it takes a very long time to see check the quality and/or mesh preview. ICEM just use one processor out of 12 (around 7%). So if it run over the whole, then I got much more speed.

i am checking with the ANSYS people in Calgary and hopefully they will give me a reply

Since I ask for the answer and I got reply, I want to share it with the others.

Only the volume meshing using the Octree approach can take advantage of the parallel option in ICEM!

In fact octree is the most resource consuming method.
