Hi all,

I went to a course on Fluent and their alternative meshing program, but I have now found out for my purposes, ICEM is much better. Sadly I am not at all familiar with it!

My situation is that I imported an STL file of a 3D locust head in to ICEM CFD. It has a very uniform nice faceted surface so I have converted this directly in to a mesh using the Edit > 'Facets -> Mesh' option. I also imported a large cuboid to act as my fluid region and I have lined up the locust head inside this, with the aim being to analyse flow over this whole model (nothing inside the head..)

I have defined parts on the fluid region for 'Inlet', 'Outlet', and 'Wall'

I have also used 'Create Body' and using material point option I selected relevant points for the fluid region and separately for the locust head.

So, to make things clear, in the control tree, I have 'Inlet', 'Outlet', 'Wall', and 'Head' under parts, and also have a Mesh > Shells entry because I converted the facets to mesh.

Now I have several questions:

1. Do I now delete the head geometry (to just retain the head mesh)?

2. How do I create a volume mesh for my fluid region? When I try and mesh anything, it just builds up a volume mesh inside the HEAD, with nothing in the fluid region. I don't think I even need a volume mesh inside the head, is that correct?

Any help is greatly appreciated, apologies if any of these questions seem terribly stupid!

Many thanks in advance,

Fergus

I should also add, I also don't have a surface mesh on the fluid region either, and would also appreciate any help in achieving this first!
