I'm trying to set up a simple model of a chamber with a filter running down the middle of it. Air is forced through the filter, and I'm measuring the pressure drop across the filter. Here's what I know:

• Filter permeability = 7.8e-11 m^2
• Filter thickness = 0.003048 m
• Filter area = 0.0001834 m^2

My question: how do I set up this porous media material in the engineering database? I can share files if necessary.
