no heat-transfer between 2 solid blocks

obic · January 30, 2012, 09:12

Hi,

I'm quite new to fluent and now trying to understand heat transfer modeling. My current setup is the following:

- 2 separate blocks of solids of different materials (aluminium and copper)
- the wall between them is a two sided-wall
- Energy equation is enabled, the simulation is transient
- i tried all options: wall boundary conditions interior, coupled and wall with heat transfer
-solution initialized to 300K, one block patched to 400K

the problem is that both blocks keep their initial temperature even after a lot of time has passsed in the simulation.

what do I have to change in my setup

Thanks for your help

You may use a common face for the two blocks with the coupled option.
The common wall will be divided in two under Fluent (wall and shadow-wall)...
