[ICEM] ICEM Unstructured Mesh Body Problem

bjkozn · June 8, 2019, 06:53

Hi all,
I am new in ICEM and trying to model aircraft with propeller. In order to do that I choose sliding mesh and am trying to create unstructured mesh since blocking will be cost too much time. First, I tried to create meshes for propeller and its boundary separately. But when create volume mesh, it creates volume meshes inside the propeller even I have created body for fluid. My curves are red and I could not find the problem. Could you help me?

I am adding link and some pictures of project below.

Thank you so much

You are using the Octree volume mesh method. Put an OFRN material point inside the propeller. I assume you have a LIVE material point in the fluid where you want the mesh. See if that helps

Maybe a stupid question, but where are your surfaces? Can you show these?
They are more important than curves. Probably your propellor is not closed
