Subject: meshing problem in furnace analysis

Hi everybody
I am doing an analysis of annealing furnace.
My object is to find out the temperature distribution in the cavity of the
furnace which is 14' * 14' * 20'.
Four burners on each 14' * 20' faces are installed 1' from bottom.

A section 7' * 14' * 20' can be taken due to symmetry.
the walls of the furnace consists of 1' thick fireclay bricks, then 2.5
inches thick rockwool and then 6mm thick steell shell.
i want to do 3-D analysis.
The problem i am having is in meshing of the model especially at the
corners.
I am taking solid 90 for conduction and convection and surface 22 for
radiation.
I am attaching a file of a 3D section of the furnace in word97 format.
* how to mesh the walls of the furnace, i.e. bricks, rockwool and shell , i
mean how can i deal with the mesh at the corners of the wall, either i have
to take the corners as a seperate volume of square x-section at the corners(
as i have shown in the figure for Bricks only with bold lines) of the wall
or is there any other way to deal with it.
*to find out the temperature distribution in the cavity , should i have to
resort to flotran cfd or can it be done in thermal analysis by meshing air
in the cavith with solid 90.

any help in this regard shall be highly appreciated
Regards
From
Yasir.
