Hi all,
I’ve loaded a CAD model (STEP file) in ICEM CFD: it is a complete impeller but I want to use only one channel, so I have deleted unnecessary stuff and I created a closed volume containing one blade delimited by surfaces each one obtained rotating the other.
The problem is that when I set the rotational periodicity and I try to build a volume mesh something strange happens as you can see in the attached image. I was expecting the mesher just to fill the volume with
tetras not to change the geometry
Can someone help me?
Thank you.
