Guides to create 3D fibrous porous media geometry file for LBM
 

Hello all
I'm new to this forum.
I want to calculate the "permeability" in some ordered/random 3D fibrous porous media. But i don't know how to create geometry files which describes the mentioned and similar geometries.
Could you please kindly help me how to create such geometries?

I mean geometries like these two samples to be entered as an input file:
