CFD Online Discussion Forums - [Commercial meshers] How to separate fluid zones?

Hello everyone!

I have a fluid domain which is separated into two zones (one of them should be set as porous) and I meshed it in gambit creating two different "continuum types". At the end of the .msh file there is

Code:

(0 "Zones:")

(45 (2 fluid zone2)())

(45 (3 fluid zone1)())

(45 (4 wall wall_in)())

(45 (5 wall wall_out)())

(45 (6 pressure-outlet outlet)())

(45 (7 velocity-inlet inlet)())

(45 (9 interior default-interior)())

so I guess the two zones are set correctly. When I convert the mesh to OF I lose this division and I can only find one cell zone as I can read from the cellZone file contained in polyMesh:

Code:

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //



0

()



// ************************************************************************* //

Is there a problem in the mesh? Should I specify something in the conversion? Thank you for any help, I lost lot of time trying to fix this without succeeding.. :(
