best way ICEM 12.1 -> openFoam1.7.1
 
Welcome foamers,

from a few days I try convert mesh from ICEM to openfoam, but it's goes wrong.. I created a model to porous case

http://img692.imageshack.us/img692/4484/pipe1c.jpg

when I convert this mesh to openfoam i lose my porous zone.. what should I do? :confused:

I try:

fluentV6/nastran =>fluent.mesh
ideas/ansys => ideas

I find solution.. and now I have porous_zone, but now I have new problem :(
when I try to calculate, it's give me only one time step.. :(

what;s can be wrong ? ;/
