Surfaces lost from ICEM to CFX-Pre 5.7

Mark

Hi!

My model is a plate with a hole. One side of the plate is supposed to have a constant heat flux as boundary condition. Air should flow through the hole and take some heat of the plate. After meshing the geometry in ICEM two "CREATED MATERIAL" appear, standing for the meshed Volumes of the plate and the air. Now the two problems: In ICEM exist two surfaces (FRONT and BACK) of the plate. But when I open it in CFX these two surfaces don't exist anymore. There is just the "CREATED MATERIAL" and I can't differ between the surfaces by setting the boundary conditions.

The bigger problem is that after I started [Write a solver file] CFX creates for both domains (fluid and solid) a default boundary condition named "Default 1 Side 'domain name' Part 1 (or 2)". The type of boundary condition is interface and it is in conflict with the boundary condition that I already set to the "CREATED MATERIAL".

Please help me with these two problems.

Thanks,

Mark
