coordinate system poroussimplefoam

I am trying to simulate a multitubular reactor (a cylinder including about 30.000 single tubes) using a porous media with only one direction of permeability. As far as I've understood the porousSimpleFoam solver I have to create a coordinate system which defines the directions of the Darcy coefficient.
In my case the fluid flows from the top of the reactor down through the porous media. Therefore my velocity at the inlet is currently (0 -1 0).
Now there is my problem:
I defined the coordinate system like this:
e1 (0 -1 0)
e2 (1 0 0)
and D = (1e10 1e5 1e10)
I use this high values for x and z as I don't want the fluid to be able to flow into these directions. Unfortunately my approach does not seem to work. Do I have to use another coordinate system or do I need to change the Darcy vector?
Thanks in advance,
