Hi guys,

i got a weird problem !!!
i wanna simulate a 3D equilateral triangular duct which is consisted of 2 zone. (i made it 2 zone since i wanna use lower zone for porous media.)

the problem is when i make the duct into 2 zone, the temp contour lines is not gonna be continuous at the interface of 2 zone, even if the 2 zone have the same properties and inlet and outlet conditions!

BUT if i merge 2 zone into 1 zone (or simply delete all cell zone boundary in GAMBIT), the problem will be solved. BUT I NEED 2 ZONE because i want to use porous media for another zone !!!

take a look please at pics below for more understanding of the problem:

temp contour (see the interface between 2 zone)



please please help, i would be so grateful
many Thanks in advance.
