Problem with a volume mesh generation
 

Dear All,

I am trying to make a model of the cleanroom with moving person (with ICEM-CFD). But there is a problem with volume meshing.
The geometry is simple (files are below) but I don't know, why is a problem with volume meshing? (surfaces are meshed well)
Does anybody have an experience with ICEM-CFD meshing? Could you tell me, where could be a problem with volume? Because I have no a big experience with ICEM-CFD (Before ICEM-CFD I have used another software)
Thanks.

I have found strange thing in meshing:
If I meshed all geometry "Hexa" - all surfaces are meshed, but volumes aren't;
The error is following: error orienting normals, perhaps there is more than one region error in output_region_boundaries.
but if I meshed all geometry "Tetra" - the volumes are meshed, but the surfaces, which are "connected", I mean surfaces which are "interface" between LEFT-INTERIOR and MOVING-MESH-FRONT-LEFT and etc. (inside the geometry model) aren't meshed. You can see it at the attached link above.

How to download the mesh file?Maybe I could help you

Hi, email is huwenshengxiaohaha@163.com. You can send the mesh to me.

For tetra meshing you have to define the interface surfaces as internal walls under part mesh setup.

Also blocking for this geometry should be pretty easy, even for a beginner. Just look for some tutorials and go for it;).

The internal wall option only applies to Octree. To mesh the interface surfaces you have to associate the faces to their corresponding surfaces.
