Hi

Your problem ist the difinition of the volumes in Gambit. The two volumes (one fluid, one porous zone) have to be seperatet by the SAME face!

So check your volumes in Gambit and make sure, that both are using the same face. If there is any face, that is not used by a volume, fluent will transform it into a wall.

to Ralf Schmidt :

thank you !you are right ,i check it in Gambit and find the two faces not use the same edge,and i konw it must use "split" to split face to faces!
