Hey,

I am pretty new to OpenFOAM. In my case i wanna simulate a multitubular reactor using the porousSimpleFoam solver. To get into OpenFOAM I started with a simulation of a 2 D plane with a porous zone in the middle. I reconfigured the angleDuctImplicit example to do so and it worked fine. Unfortunately I don't really get why.
The walls along the porosity zone are called "porosityWalls" just like in the example. Now there's the thing I don't get. How does OpenFOAM know, where the porous media is located at? In the porosityProperties file it looks something like this:

porosity1 {
cellZone: porosity;

Isn't it necessary to use the same names as in the blockMeshDikt file?

Thank you!
