How to solve 2 diferrent specify continuum types

tuw

Hi all,

Any suggestion is much appreciated!

Basically, I am modelling a solid model (with heat generation) and also the surrounding air around it. My purpose is to see:

1. the thermal distribution of the solid,

2. the temperature of the fluid and also

3. the fluid flow pattern (if i assign a certain velocity inlet to the fluid).

Therefore i would have 2 continuum zone which is specified during my session in gambit 2.2.30.

2Zones:

1. my solid - solid

2. surrounding air - fluid

For the wall boundary between the 2 zones, i use "face --> connect face" to combine the 2 faces into 1 for each coupling faces. For example, a face from the solid is combine with another similar face from the fluid. The face is then defined as internal boundary.

However, when i proceed to Fluent 6.2.16, the error as below appear:

Warning: materials in neighbor cell threads (2 and 3) of

interior zone 4 are of different types (aluminum and air).

This problem MUST be fixed before solving!
