i am simulating convective heat transfer inside the 3D closed room.for which i am using a cube room model, inside which there is a heat source. at the sides of the wall, bottom, there are two inlets and two outlets at the top. i don't have idea how to how to mesh. i will be very thankful if someone provides little hint.

thanks in advance

is your outer cube already splitted from your inside cube (source)?

Yes, i did that after going through some of the posts here.

P.S-is it correct to take inlet and outlet conditions, just the way i made, on the faces of the cube(as the are in 2D)?

I check your model.
Nothing is connectd, and/or spliited
So:
-split volume 1 with volume 2
-split face 6 with face 15 and face 16
-split face 2 with face 13
-split face 1 and 14

Then you can (or not delete the volume inside your cube (source))
Once it is done, you can go and mesh as you want

Thank you max-

i got the mesh, but i am facing problem while exporting the mesh to fluent, i am getting a WARN: boundary entity xxxx(for inlet and outlet) does not contain any valid entity........

P.S- i am generating volume mesh for source and room.
