Flow through a porous domain - domain issues

I'd like to use OpenFoam to simulate a setup that involves a swirler, a honeycomb and many more things. I managed to include most of my geometry and physics, however I'm stuck with the honeycomb.
To get started, I thought of using a simple setup, say a duct with a honeycomb, acting as a flow straightener. Having searched the forums and the tutorials, I think simpleFoam + fvOptions is the way to go for my problem, but I am stuck with the porous domain, or more specifically, the mesh.
I created a geometry in ICEM (see screenshot) with a doamin Fluid1, Porous, and Fluid2. These domains are separated by a surface.
Now to my question: How do I tell OpenFoam where the porous domain is?
1. Set the name of the POROUS domain in the fvOptions file and specify the interfaces as patches, where each computed quantity (U,p,...) has a zeroGradient boundary condition, or
2. Do I use the setTopo utility?
If option2, could someone explain (in detail, pretty please) how this is done. I can't make head and tails of what I can find in the forum/tutorials.
