Boundary condition problem in 2d mesh
 
hi All,
I made a 2d structured mesh in ICEM. I just went through tutorial and youtube video by Simon. I got everything done but when i import the mesh file. It not showing the mesh.

In the dialog box it say:
Building...
mesh
Removing 97260 unreferenced faces, zone 12.
Removing 149 unreferenced faces, zone 14.
Removing 99 unreferenced faces, zone 15.
Removing 654 unreferenced faces, zone 16.

Warning: Number of nodes read (49575) does not match number referenced (0).
Resetting counter to match the number referenced.

Warning: non-positive volumes exist.

materials,
interface,
domains,
zones,
Skipping zone wall (not referenced by grid).
Skipping zone inlet (not referenced by grid).
Skipping zone outlet (not referenced by grid).
Skipping zone airfoil (not referenced by grid).
Skipping zone int_ff (not referenced by grid).
Skipping zone ff (not referenced by grid).
Done.

I like to know what i need to do more. And where is the mistake i have done. I tried for 5 time so far :(

make sure fluid is assigned fluid in the boundary condition. and no curve is forgotten. just re-do it, it happens to me until i realize i forget i basic step...

Thanks Ali.. you are correct about the fluid.. i'll redo again but i think i need to check the boundary settings well before going to mesh.. i almost wasted two days :( i'll update soon after i finish the grid is it working or not. :)

that's not wasting, it's called learning. later you will realize it
