2D mesh extraction problem
 
Dear all,

I am new to Star ccm, and I have problem with extraction 2d mesh from a 3d region.

I have modelled a basic 3d cube using 3d modeller in Star ccm, and renamed that cubes faces arbitrary(boundary conditions of every face is set randomly as well).Cube is meshed with Trimmer+surface remesher model. It is also aligned on the x-y plane (z=0 plane) in order to meet 2d mesh extraction requirements
The problem is when I convert 3d mesh into 2d, I just get 2d boundaries without continuum ( to explain this situation clearly I have attached screenshot below) . I also checked "Heated Fin Tutorial" and I applied every step of that tutorial into my case but I couldnt get 2d mesh like heated fin tutorial

Please check attached pictures below.

Thanks in advance
any help would be deeply appreciated.
